Summarize any known primary reasons for prior inventory findings listed in this table):
In 1980, the unit included the steep cliffs of Coglan Buttes on the west border and broad,
low-angle slopes descending toward Abert Lake to the east. The majority of the unit was
broad, sagebrush-covered flats with very little topographic relief. The unit contained 23
miles of ways, some of which had historical blading. Shores Waterhole was a substantial
impact on about 2,500 acres of the unit due its large size. There were a total of five
reservoirs, several watering stations, a guzzler, and a radio repeater site located in the unit.
These disturbances were dispersed throughout the unit and collectively had a substantial
impact on the unit's natural character.
Due to the lack of vegetative and topographic screening, the unit was found to have
minimal potential for solitude. With the exception of the Coglan Buttes formation, there
1
was little opportunity for unconfined, primitive recreation. Wildlife viewing and hunting
opportunities were noted, but they were not found to be outstanding. Possible supplemental
values were noted as archaeological and geological values, though none were specifically
identified at the time.

DOCUMENTATION OF CURRENT WILDERNESS INVENTORY CONDITIONS
a. Unit Number/Name:___OR-015-096A/Coglan Buttes East____
(1) Is the unit of sufficient size? Yes _X_ No
In 2005, the BLM received a citizen proposal from the Oregon Natural Desert
Association (ONDA) for the 55,268-acre Coglan Buttes proposed Wilderness Study Area
(WSA). ONDA included in their information a narrative report, maps, photos, photo and
route logs, and GIS data. All of these materials were considered during the BLM’s
wilderness inventory process for this area. The photos submitted by ONDA were taken
in July of 2004 and June of 2005. They identified the area as having no interior routes
which met the BLM’s wilderness inventory definition of a road (see Map, p. 39 of
ONDA 2005).
Between 2008 and 2012, members of the BLM staff conducted field inventory in the area
as part of a process to update its road and wilderness inventories and to gather additional
information to supplement ONDA’s wilderness information. This included driving and
collecting photo documentation of routes and human disturbances in the area. Using both
ONDA and BLM photos, field logs, and staff field knowledge, a BLM inter-disciplinary
(ID) team completed an analysis of the main routes within the area and made boundary
road determinations.
The BLM ID team determined that several of the routes ONDA identified as “ways” are
in fact boundary roads defining inventory units. For this reason, the BLM found the
Coglan Buttes proposed WSA is not one large roadless unit, but is comprised of several
smaller inventory units (4 which met the size criteria and numerous others that did not;
see Map 2) which must be evaluated individually. The results of the route analysis are
documented in the route analysis forms contained in the wilderness evaluation file.
This evaluation focuses on the Coglan Buttes East unit (OR-015-96A). The unit is
bounded on the north by BLM Road 6124-00 (Sand Hollow), on the east and south by the
BLM Road 6151-A0 (Big Basin), and on the west by BLM Road 6124-A0 (Coglan
Butte) (Map 2). Refer to the route analysis forms, photos, photo logs, and BLM ID team
minutes in the wilderness inventory file for additional supporting information regarding
these boundary determinations.
Following boundary determination, the BLM ID team evaluated the wilderness
characteristics within the unit. These results are contained in the following sections.

Additional background on the process that the BLM ID team followed during this
evaluation is contained in the ID team meeting notes and the document, Wilderness
Inventory Process for the Lakeview Resource Area, BLM. Both documents are contained
in the wilderness inventory file.
DESCRIPTION OF CURRENT CONDITIONS: The unit is located approximately 12
north of Valley Falls and about 4 miles west of Lake Abert (Map 1). The triangularshaped inventory unit is approximately 8 miles long, ranges from 1 to 5 miles wide, and
contains approximately 11,029 acres of BLM-administered lands (Map 2). This unit is
much smaller than the original unit evaluated in 1980. The topography has not changed
since the original inventory and consists of low-angle slopes descending towards Lake
Abert with little topographic relief. The vegetation has not changed substantially and
consists of sagebrush dominated plant communities.
(2) Is the unit in a natural condition? Yes _ X No _____
N/A_______
In 2005, ONDA (pages 36-37) found their much larger Coglan Buttes proposed WSA to
be primarily affected by the forces of nature. However, for the reasons described above,
the BLM found that this proposal did not represent one large roadless unit, but is in fact
comprised of several smaller inventory units which must be evaluated individually.
The unit boundaries have changed since the 1980 inventory. The Coglan Buttes East
(OR-015-096A) unit comprises the northeastern third of the historic Coglan Buttes (1-96)
unit. In 1980, the larger Coglan Buttes unit (1-96) did not meet the naturalness criteria
(See Form 1). The smaller unit currently contains 0.6 miles of pipeline and 1 associated
water trough, and 3 waterholes. There are about 5.3 miles of open, primitive motorized
routes and another 4.7 miles of reclaiming routes within the unit. Additionally, 12.8
miles of pasture division fence and 355 acres of crested wheatgrass seeding are present
within the unit. These disturbances are distributed around the periphery of the unit, but
continue to be substantially noticeable in close proximity (up to a quarter mile), and
cannot be logically excluded from the unit boundary (Map 2).
Based upon all of the available information including photos, staff knowledge, and field
review, the BLM ID team concluded that the natural character of this unit has not
improved dramatically since 1980 and is currently in a marginally natural condition.
(3) Does the unit (or the remainder of the unit if a portion has been excluded due to
unnaturalness and the remainder is of sufficient size) have outstanding opportunities
for solitude? Yes
No
X
N/A________
In 2005, ONDA (page 37) found their much larger Coglan Buttes proposed WSA
provided an outstanding opportunity for solitude due to the topography present in the
Coglan Buttes formation and large unit size. However, for the reasons described above,
the BLM found that this proposal did not represent one large roadless unit, but is in fact
comprised of several smaller inventory units which must be evaluated individually.
3
In 1980, the inventory noted that the lack of lack of topographic relief on the northeast
side of the larger Coglan Buttes (1-96) unit provided a very poor opportunity for an
individual to avoid the sights, sounds, and presence of others. The present unit is smaller
and excludes the Coglan Buttes formation to the southwest and, as a result, is relatively
flat and open. This current unit is smaller and lacks both topographic or tall vegetative
screening where one can avoid the presence of others (see Map 3). Further, the area is
currently open to off-highway vehicle use (see Map R-7 of Lakeview RMP/ROD) and is
managed to provide motorized access, along the existing, open boundary roads and
primitive motorized routes inside the unit (Map 2). This motorized access increases the
likelihood of encountering other people visiting the unit. The noise associated with
motorized activity may further diminish the solitude experience for those visitors
attempting to get away from others.
Based upon all of the available information including photos, staff knowledge, and field
review, the BLM ID team concluded that the current smaller unit lacks an outstanding
opportunity for solitude.
(4) Does the unit (or the remainder of the unit if a portion has been excluded due to
unnaturalness and the remainder is of sufficient size) have outstanding opportunities
for primitive and unconfined recreation?
Yes
No
X
N/A________
In 2005, ONDA (page 37) found their much larger Coglan Buttes proposed WSA
provided an outstanding opportunity for primitive and unconfined recreation including
hiking, backpacking, photography, horseback riding, and wildlife viewing. However, for
the reasons described above, the BLM found that this proposal did not represent one large
roadless unit, but is in fact comprised of several smaller inventory units which must be
evaluated individually.
In 1980, the larger Coglan Buttes unit (1-96) was noted as having some limited wildlife
viewing and hunting opportunities associated with the Coglan Buttes formation to the
southwest (see Form 1). However, this formation is not part of the current unit. The ID
team found that the current unit is smaller and provides some opportunities for fall
antelope hunting and wildlife viewing. These primitive recreation opportunities were
limited and were similar to opportunities available throughout much of the surrounding
area. The unit did not offer any single unique primitive recreation opportunity or a
unique diversity of primitive recreation opportunities. In addition, the unit is currently
being managed to provide semi-primitive motorized recreational experiences and is open
to off-highway vehicle use (see Lakeview RMP/ROD Maps R-3 and R-7). Most existing
recreational use is indirectly associated with this motorized access.
Based upon all of the available information including photos, staff knowledge, and field
review, the BLM ID team concluded that the unit continues to lack outstanding
opportunities for primitive and unconfined recreation.
(5) Does the unit have supplemental values? Yes
4
No
N/A___X_____
Due to the unit failing to meet the all appropriate wilderness criteria, supplemental values
were not evaluated.

Between 2008 and 2012, members of the BLM staff conducted field inventory in the area
as part of a process to update its road and wilderness inventories and to gather additional

This evaluation focuses on the Coglan Buttes West unit (OR-015-096B). The unit is
bounded on the north by BLM Road 6124-00 (Sand Hollow), on the east by BLM Roads
6124-A0 (Coglan Butte) and 6154-00 (Big Basin), on the west by County Road 2-7 (Red
House Lane) and one interim numbered road (2100), and on the south by one interim
numbered road (6154-F). See Map 2.

Following boundary determination, the BLM ID team evaluated the wilderness
characteristics within each unit. These results are contained in the following sections.
Additional background on the process that the BLM ID team followed during this
evaluation is contained in the document Wilderness Inventory Maintenance Process for
the Lakeview Resource Area, BLM contained in the wilderness inventory file.
DESCRIPTION OF CURRENT CONDITIONS: The unit is approximately 14.5 miles
long and averages 3 miles in width. The unit is located about 8 miles east of the town of
Paisley (Map 1). The unit contains approximately 22,006 acres of BLM-administered
lands (Map 2). The topography can still be described as sagebrush flats along the east and
west base of the steep cliffs of the Coglan Buttes formation, which run generally north to
south through the center of the unit.
(2) Is the unit in a natural condition? Yes
No _X___
N/A_______
ONDA’s 2005 inventory concluded that their proposed 55,268-acre Coglan Buttes
proposed WSA was affected primarily by the forces of nature. However, as described
above, the BLM determined that this proposal is not one large roadless area, but is
comprised of several smaller inventory units, which must be evaluated individually.
The unit boundary has changed since the 1980 inventory. The Coglan Buttes West (OR015-096B) unit comprises the western two-thirds of the historic Coglan Buttes (1-96)
unit. In 1980, the larger Coglan Buttes unit (1-96) did not meet the naturalness criteria
(See Form 1). Within this smaller unit there are currently 10 wildlife guzzlers, 4
constructed waterholes, a reservoir, and a well. There are roughly 19 miles of open,
primitive motorized routes within the unit, along with 0.25 miles of open motorized trail,
and 3 miles of reclaiming routes. Additionally, there are about 7.7 miles of pasture
division fence, one open mineral pit (occupying about 20 acres), and 5 abandoned mine
sites (approximately 5 acres) within the unit. These man-made developments are spread
across the unit, are substantially noticeable within close distance (up to a quarter mile),
and cannot be logically excluded from the unit boundary (Map 2). In addition, there is a
radio repeater site with an associated overhead utility line “cherry-stemmed” just outside
the unit boundary on the southern end. Though those developments are technically
outside the unit boundary, they are substantially noticeable within the southwestern
portion of the unit.
Based on a review of all the available information including photos, staff knowledge, and
field review, the BLM ID team concluded that while the unit size has decreased, the
overall natural character within the area has changed little since the original inventory
and the unit is still in a unnatural condition where the imprints of man are substantially
noticeable.

Summarize any known primary reasons for prior inventory findings listed in this table):
In 1980, this historic unit met the minimum size criteria. The inventory noted the presence
of a 2,400-acre crested wheatgrass seeding in the northeast, the old Hotchkiss Road cut
banks and associated scarring in the center of the unit, and one way and a gravel pit in the
southwest which impacted the unit’s natural character. Due to the unit’s exposure across its
eastern side and the above intrusions, it was determined that that the unit was not primarily
affected by the forces of nature.
Opportunities for solitude were described as limited in the buttes and side canyons on the
west edge of the unit. The eastern portion consisted of broad expanses of flat terrain
offering limited vegetative cover or topographic relief. For these reasons, the unit did not
offer outstanding opportunities for solitude. The unit offered some limited recreational
1
opportunities for wildlife observation, especially raptors along the west side of the cliffs,
but the unit’s size and narrow shape limited the degree to which one could pursue other
forms of primitive recreation. The unit was found not to have outstanding recreation
opportunities. Possible supplemental values were noted as archaeological values, though
none were specifically identified at the time.

This evaluation focuses on the Abert Burn North (OR-015-98A) unit. The unit is
bounded by BLM Roads 6154-00 (Big Basin) to the west, 6154-B0 (Abert Burn) to the
north, 6104-A0 (Clark Ranch) to the east, and 6154-A0 (Hotchkiss) to the south (Map 2).
Refer to the route analysis forms, photos, photo logs, and BLM ID team minutes in the
wilderness inventory file for additional supporting information regarding these boundary
determinations.

Following boundary determination, the BLM ID team evaluated the wilderness
characteristics within the unit. These results are contained in the following sections.
Additional background on the process that the BLM ID team followed during this
evaluation is contained in the document Wilderness Inventory Maintenance Process for
the Lakeview Resource Area, BLM contained in the wilderness inventory file.
DESCRIPTION OF CURRENT CONDITIONS: The unit is located about 7.5 miles
north of Valley Falls (Map 1). The unit is approximately 6.7 miles long, varies in width
from 0.5 to 3 miles, and contains approximately 9,004 acres of BLM-administered lands.
The topography has not changed since the original inventory and can still be described as
a large fault block with a steep escarpment to the west with a low angle slope falling
away toward the shore of Lake Abert on the east.
(2) Is the unit in a natural condition? Yes _X No ____
N/A_______
In 2005, ONDA (pages 36-37) found their much larger Coglan Buttes proposed WSA to
be primarily affected by the forces of nature. However, for the reasons described above,
the BLM found that this proposal did not represent one large roadless unit, but is in fact
comprised of several smaller inventory units which must be evaluated individually.
The unit boundaries have changed since the 1980 inventory. The current Abert Burn
North (OR-015-098A) unit comprises roughly the northern half of the historic 1-98 unit.
About a third of the unit burned in 1971 and was seeded to crested wheatgrass. This
seeding remains evident today, but is being invaded by sagebrush and is returning to a
more natural appearing condition. About a third of the unit burned in 1986, but was
allowed to revegetate naturally. Current vegetation consists primarily of grasses and
sagebrush.
In 1996, the BLM designated Lake Abert and surrounding public lands as an Area of
Critical Environmental Concern (ACEC). The ACEC management plan recognized and
provided special management for four important resource values or processes in this area
including wildlife resources, cultural resources, scenic values, and ecological processes.
The western edge of the ACEC overlaps with the eastern edge of this inventory unit (see
Map 2). These wildlife values and ecological processes were primarily associated with
Lake Abert proper, which lies to the east and just outside of the unit boundary.
Within this smaller unit there are 4 guzzlers, 0.15 miles of pipelines and 1 associated
water trough. There are roughly 1.5 miles of open, primitive motorized routes along with
another 4 miles of reclaiming routes within the unit. Additionally, 2.9 miles of pasture
division fence is present within the unit. There are 2 abandoned mining sites covering
several acres. These man-made developments are spread across the unit (Map 2), are
substantially noticeable within close distances (up to a quarter mile) and less noticeable
from farther distances. However, the unit currently appears to be primarily affected by
the forces of nature.

Based on a review of all the available information including photos, staff knowledge, and
field review, the BLM ID team concluded that the unit was in a natural condition where
the imprint of man is substantially unnoticeable.
(3) Does the unit (or the remainder of the unit if a portion has been excluded due to

No

N/A________
In 2005, ONDA (page 37) found their much larger Coglan Buttes proposed WSA
provided an outstanding opportunity for solitude due to the topography present in the
Coglan Buttes formation and large unit size. However, for the reasons described above,
the BLM found that this proposal did not represent one large roadless unit, but is in fact
comprised of several smaller inventory units which must be evaluated individually.
The 1980 inventory noted that the larger 1-98 unit had limited opportunities for solitude
(see Form 1). The current unit is smaller, has predominantly broad, flat terrain and lacks
tall vegetative screening. There is some topographic screening along the western edge of
the unit associated with the Coglan Buttes formation, but the eastern face is relatively
exposed and provides few places where one can avoid the presence of others (see Map 3).
Further, the area is currently open to off-highway vehicle use (see Map R-7 of Lakeview
RMP/ROD) and is managed to provide motorized access, particularly along the existing,
open boundary roads and primitive motorized routes inside the unit (see Map 2). This
motorized access increases the likelihood of encountering other people visiting the unit.
The noise associated with motorized activity may further diminish the solitude
experience for those visitors attempting to get away from others.
Based on a review of all the available information, the ID team concluded that
opportunities for solitude have not changed since 1980 and the current, smaller unit still
does not have an outstanding opportunity for solitude.

provided an outstanding opportunity for primitive and unconfined recreation including
hiking, backpacking, photography, horseback riding, and wildlife viewing. However, for
the reasons described above, the BLM found that this proposal did not represent one large
roadless unit, but is in fact comprised of several smaller inventory units which must be
evaluated individually.
The BLM ID Team considered the primitive recreation opportunities identified in 1980
(see Form 1) and those identified by ONDA and determined that the current unit is
smaller, and hunting and wildlife observation continue to be the primary primitive
recreation opportunities available in the area. These primitive recreation opportunities
4
were similar to opportunities available throughout much of the surrounding area. The
unit did not offer any single unique primitive recreation opportunity or a unique diversity
of primitive recreation opportunities. In addition, the BLM currently manages the area to
provide semi-primitive motorized recreational experiences and is open off-highway
vehicle use (see Maps R-3 and R-7 of Lakeview RMP/ROD). Most existing recreational
use is indirectly associated with this motorized access.
Based upon all of the available information including photos, staff knowledge, and field
review, the BLM ID team concluded that the unit continues to lack outstanding
opportunities for primitive and unconfined recreation.
(5) Does the unit have supplemental values? Yes
No
N/A___X___
Since the unit did not meet all the required criteria, supplemental values were not
evaluated.

Summarize any known primary reasons for prior inventory findings listed in this table):
In 1980, this historic unit met the minimum size criteria. The inventory noted the presence
of a 2,400-acre crested wheatgrass seeding in the northeast, the old Hotchkiss Road cut
banks and associated scarring in the center of the unit, and one way and a gravel pit in the
southwest which impacted the unit’s natural character. Due to the unit’s exposure across its
eastern side and the above intrusions, it was determined that that the unit was not primarily
affected by the forces of nature.
Opportunities for solitude were described as limited in the buttes and side canyons on the
west edge of the unit. The eastern portion consisted of broad expanses of flat terrain
offering limited vegetative cover or topographic relief. For these reasons, the unit did not
offer outstanding opportunities for solitude. The unit offered some limited recreational
1
opportunities for wildlife observation, especially raptors along the west side of the cliffs,
but the unit’s size and narrow shape limited the degree to which one could pursue other
forms of primitive recreation. The unit was found not to have outstanding recreation
opportunities. Possible supplemental values were noted as archaeological values, though
none were specifically identified at the time.

(1) Is the unit of sufficient size? Yes _X
No
In 2005, the BLM received a citizen proposal from the Oregon Natural Desert
Association (ONDA) for the 55,268-acre Coglan Buttes proposed Wilderness Study Area
(WSA). ONDA included in their information a narrative report, maps, photos, photo and
route logs, and GIS data. All of these materials were considered during the BLM’s
wilderness inventory process for this area. The photos submitted by ONDA were taken
in July of 2004 and June of 2005. They identified the area as having no interior routes
which met the BLM’s wilderness inventory definition of a road (see Map, p. 39 of
ONDA 2005).
Between 2008 and 2012, members of the BLM staff conducted field inventory in the area
as part of a process to update its road and wilderness inventories and to gather additional
information to supplement ONDA’s wilderness information. This included driving and
collecting photo documentation of routes and human disturbances in the area. Using both
ONDA and BLM photos, field logs, and staff field knowledge, a BLM inter-disciplinary
(ID) team completed an analysis of the main routes within the area and made boundary
road determinations.
The BLM ID team determined that several of the routes ONDA identified as “ways” are
in fact boundary roads defining inventory units. For this reason, the BLM found the
Coglan Buttes proposed WSA is not one large roadless unit, but is comprised of several
smaller inventory units (4 which met the size criteria and numerous others that did not;
see Map 2) which must be evaluated individually. The results of the route analysis are
documented in the route analysis forms contained in the wilderness evaluation file.
This evaluation focuses on the Abert Burn South unit (OR-015-98B). The unit is
bounded by BLM road 6154-00 (Big Basin) to the west, 6104-A0 (Clark Ranch) to the
east, and 6154-A0 (Hotchkiss) to the north (Map 2). Refer to the route analysis forms,
photos, photo logs, and BLM ID team minutes in the wilderness inventory file for
additional supporting information regarding these boundary determinations.
2
Following boundary determination, the BLM ID team evaluated the wilderness
characteristics within the unit. These results are contained in the following sections.
Additional background on the process that the BLM ID team followed during this
evaluation is contained in the document Wilderness Inventory Maintenance Process for
the Lakeview Resource Area, BLM contained in the wilderness inventory file.
DESCRIPTION OF CURRENT CONDITIONS: The unit is located about 3 miles north
of Valley Falls (Map 1), is approximately 8 miles long, is about 3 miles in width at the
center, and tapers at the north and south ends. The unit contains approximately 9,247
acres of BLM-administered lands. The topography has not changed since the original
inventory and can still be described as a large fault block with a steep escarpment to the
southwest with a low angle slope falling away to the northeast towards the shore of Lake
Abert.
(2) Is the unit in a natural condition? Yes __X_ No _____
N/A_______
In 2005, ONDA (pages 36-37) found their much larger Coglan Buttes proposed WSA to
be primarily affected by the forces of nature. However, for the reasons described above,
the BLM found that this proposal did not represent one large roadless unit, but is in fact
comprised of several smaller inventory units which must be evaluated individually.
The unit boundaries have changed since the original inventory. The current Abert Burn
South (OR-015-098B) unit comprises roughly the southern half of the historic 1-98 unit.
The majority of the unit burned in 1986, but was allowed to revegetate naturally. Current
vegetation consists primarily of grasses and sagebrush.
In 1996, the BLM designated Lake Abert and surrounding public lands as an Area of
Critical Environmental Concern (ACEC). The ACEC management plan recognized and
provided special management for four important resource values or processes in this area
including wildlife resources, cultural resources, scenic values, and ecological processes.
The western edge of the ACEC overlaps with the eastern edge of this inventory unit (see
Map 2). These wildlife values and ecological processes were primarily associated with
Lake Abert proper, which lies to the east and just outside of the unit boundary.
Within this smaller unit there is 1 wildlife guzzler and 3 wells with associated troughs.
There is one mineral pit totaling less than an acre. There are approximately 7.6 miles of
open, primitive motorized routes within the unit. Additionally 15 miles of pasture
division fence is present and located mostly near the perimeter of the unit. These manmade developments are spread across the unit, are substantially noticeable within close
distances (up to a quarter mile) and less noticeable from farther distances. The majority
of these disturbances are located primarily around the unit periphery. Currently the unit
appears to be primarily affected by the forces of nature.
Based on a review of all the available information including photos, staff knowledge, and
field review, the BLM ID team concluded that the unit is generally in a natural condition
where the imprint of man is substantially noticeable.

N/A_______
In 2005, ONDA (page 37) found their much larger Coglan Buttes proposed WSA
provided an outstanding opportunity for solitude due to the topography present in the
Coglan Buttes formation and large unit size. However, for the reasons described above,
the BLM found that this proposal did not represent one large roadless unit, but is in fact
comprised of several smaller inventory units which must be evaluated individually.
The 1980 inventory noted that the larger 1-98 unit had limited opportunities for solitude
(see Form 1). The current unit is smaller, has predominantly broad, flat terrain with
limited topographic relief on the northeastern half, and lacks tall vegetative screening
throughout the unit. The southwestern half of the unit has some topographic relief related
to the Coglan Buttes formation, but the southwestern side is completely exposed to
Highway 31 (see Map 3). There are small pockets within the unit where one can avoid
the presence of others, but these are limited to the northeastern slopes and side canyons of
the Coglan Buttes formation. Further, the area is currently open to off-highway vehicle
use (see Map R-7 of Lakeview RMP/ROD) and is managed to provide motorized access,
particularly along the existing, open boundary roads and primitive motorized routes
inside the unit (see Map 2). This motorized access increases the likelihood of
encountering other people visiting the unit. The noise associated with motorized activity
may further diminish the solitude experience.
Based on a review of all the available information, the ID team concluded that
opportunities for solitude have not changed since 1980 and the current, smaller unit still
does not have an outstanding opportunity for solitude.
(4) Does the unit (or the remainder of the unit if a portion has been excluded due to
unnaturalness and the remainder is of sufficient size) have outstanding opportunities
for primitive and unconfined recreation?
Yes

For this reason, the BLM found the Coglan Buttes proposed WSA is not one large
roadless unit, but is comprised of several smaller inventory units, 4 which met the size
criteria and 12 others that did not (see Map 2). This evaluation focuses on the 12 small,
unnumbered units, all of which are less than 5,000 acres in size and failed to meet the
size criteria or any of the exceptions to the size criteria. Based on this determination
there was no need for the BLM ID team to evaluate these units further.
Additional background on the process that the BLM ID team followed during this
evaluation is contained in the document Wilderness Inventory Maintenance Process for
the Lakeview Resource Area, BLM contained in the wilderness inventory file.
DESCRIPTION OF CURRENT CONDITIONS: These units are scattered throughout
the Coglan Buttes area and vary from 2.5 to 15 miles north of Valley Falls. Many are
located along Highway 31 or along the western edge of the evaluation area (see Maps 1
and 2).
