Summarize any known primary reasons for prior inventory findings listed in this table:
In 1980, unit 1-134 was broken into 2 sub-units along Road 6106-B0. Sub-unit 1-134A contained
approximately 3,360 acres and was not evaluated further. Sub-unit 1-134B consisted of about 22,080
acres that was described as a generally flat with some broken basalt rims and large flats at different
elevations along with some smaller hills. The major topographic feature is Lone Grave Butte which rises
to 6,150 feet in elevation. This unit is long and narrow and rise gradually in elevation from south to
north. Vegetation communities were primarily sagebrush. The unit contained approximately 13 miles of
vehicle ways and a two mile fenceline up the south slope of Long Grave Butte, but overall was in a
natural condition. The somewhat broken terrain provided some opportunity to find solitude. However,
the broad expanses between elevation changes left one exposed to others. For this reason, solitude
opportunities were no found to be outstanding. The unit was noted as providing big game hunting and
winter trapping, but these were associated with motorized vehicle access. The unit provided some
opportunity for hiking and wildlife observation, but these were not found to be outstanding. No
supplemental values were noted.

(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 a 424,570-acre area they referred to as Hart Mountain 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 update for this area. The photos submitted by ONDA were taken in 2004. They
identified this large area as having no interior routes which met the BLM wilderness inventory
definition of a road (p. 87-120 of ONDA 2005).
Between 2008 and 2012, members of BLM’s staff conducted field inventory in the area as part
of a process to update both its road and wilderness inventories and to gather additional
information to supplement ONDA’s wilderness information. This included driving and
collecting photo documentation of the 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
determinations in 2012.
The BLM ID team determined that several of the routes ONDA identified as “ways” are, in fact,
roads defining inventory unit boundaries. For this reason, the BLM found that the proposed
WSA is not one large roadless unit, but is comprised of several smaller inventory units, 3 of
which met the size criteria and 6 others that did not (Map 2). The 3 units which met the size
criteria have been evaluated separately.
This evaluation focuses on the Lone Grave Butte North inventory unit (OR-015-134B) which is
bounded by BLM Road 6176-00 and private lands on the east, 6176-K0 and private lands on the
north, and 6176-L0, interim numbered road 6176-LG, and National Wildlife Refuge lands on the
west. Refer to the route analysis forms, photos, photo logs, and BLM ID team meeting notes in
the wilderness inventory file for additional supporting information regarding these boundary
determinations. 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:
This inventory unit is located immediately adjacent to the southeast corner of the Hart Mountain
National Antelope Refuge (Map 1). Since the 1980 inventory, the historic Lone Grave Butte unit
(1-134B) was divided into two smaller units (Lone Grave Butte North and Lone Grave Butte
South) by two roads (6176-L0 and interim number 6176-LG) which the ID team determined
were boundary roads. The Lone Grave Butte North unit (OR-015-144B) contains approximately
2
19,587 acres of public land and 280 acres of private lands. The southeastern end of the unit is
dominated by Lone Grave Butte which rises from an elevation of 5,400 feet up to 6,500 feet.
The northern end of the unit in comprised of low rolling hills with interspersed rims and flat
mesas. Vegetation in the unit is predominantly sagebrush. A prescribed fire was completed in
the eastern central portion of the unit in 1999 and that area is predominantly vegetated with
grasses (Map 2).
(2) Is the unit in a natural condition? Yes _X_
No __ __
N/A _____
ONDA found their larger proposed WSA to be in a natural condition, primarily affected by the
forces of nature (p. 92-93 of ONDA 2005). However, as noted above, the BLM found that this
proposed WSA is not one large roadless unit, but is comprised of several smaller inventory units,
within which the natural character must be evaluated individually.
Since the initial inventory in 1980, there have been some additional man-made developments
noted within the inventory unit. Today, there are approximately 8.5 miles of primitive motorized
routes that intrude into the unit. There are also about 1.8 miles of reclaiming routes, 5 water
developments, and 0.7 miles of pasture division fence (Map 2). All of these features are
noticeable from close proximity, but the overall size of the unit and the juxtaposition of the manmade features leave this unit in generally natural condition as viewed by the casual observer.
For these reasons, the BLM ID team concluded that the current unit is predominantly in a natural
condition where the works of man are substantially unnoticeable.
(3) Does the unit have outstanding opportunities for solitude?
Yes_____No _X__ N/A _____
ONDA found that their proposed WSA had outstanding opportunities for solitude, primarily
because of the large size of the proposal (p. 93 of ONDA 2005). However, as noted above, the
BLM found that this proposed WSA is not one large roadless unit, but is comprised of several
smaller inventory units, within which the opportunities for solitude must be evaluated
individually.
While topography and vegetation have not changed much, the unit is substantially smaller
compared to the initial inventory completed in 1980. The smaller unit does offer some
opportunities for solitude among the broken rims and canyons scattered across the northern end
of the unit. However, broad expanses of relatively flat, open terrain covered by low growing
vegetation still leave the visitor exposed to others across much of the unit. The slopes of Lone
Grave Butte are also relatively open and exposed on all sides to visitors in the southeast portion
of the unit, particularly visitors traveling along Roads 6176-00 and 6176-L0.
Although there are some opportunities for solitude within the inventory unit, the BLM ID team
determined these opportunities have not improved since 1980, are very limited or have actually
diminished due to smaller unit size, and therefore, the unit continues to lack outstanding
opportunities for solitude.
3
(4) Does the unit have outstanding opportunities for primitive and unconfined recreation?
Yes _____
No __X__
N/A _____
ONDA noted the potential for hunting, hiking, backpacking, wildlife observation, photography,
and horseback riding within their larger proposed WSA and found it to be outstanding (p. 93 of
ONDA 2005). However, as noted above, the BLM found that this proposed WSA is not one
large roadless unit, but is comprised of several smaller inventory units, within which the
opportunities for primitive recreation must be evaluated individually.
The ID team noted the unit continues to offer some limited opportunities for hunting, trapping,
hiking, wildlife observation, and horseback riding, but these opportunities have been diminished
by the smaller unit size. These opportunities are similar to those available on other public lands
in the general area. The unit does not offer either a single unique primitive recreational
opportunity or a diversity of primitive recreation opportunities.
For these reasons, the BLM ID team determined that the primitive recreation opportunities
within the unit have not improved substantially since 1980, and therefore, the inventory unit
continues to lack an outstanding opportunity for primitive and unconfined recreation.
(5) Does the unit have supplemental values? Yes _____ No _ __
NA __X__
The BLM ID team did not evaluate supplemental values, as the unit failed to meet the minimum
wilderness criteria.

(1-134B) was divided into two smaller units (Lone Grave Butte North and Lone Grave Butte
2
South) by two roads (6176-L0 and interim number 6176-LG) which the ID team determined
were boundary roads. The Lone Grave South unit contains about 11,831 acres of public lands.
Low rolling hills and one canyon are located in the north and east sides of the unit. Shirk Lake
and dry lakebed flat cover the south portion of the unit. This lake and the surrounding dry
lakebed are about four miles long and one-half mile wide. Vegetation on the southern end of the
unit is comprised of sagebrush and low-growing grasses. Vegetation on the northern end of the
unit is predominantly sagebrush.

proposed WSA is not one large roadless unit, but is comprised of several smaller inventory units,
within which the natural character must be evaluated individually.
Since the initial inventory was completed in 1980, there have been some changes in the natural
character of the unit. A jurisdictional transfer of lands managed by the U.S. Fish and Wildlife
Service was conducted in 1998. As a result, an historic ranch (Shirk Ranch) came under BLM
management. This ranch and its surrounding structures lie directly adjacent to Shirk Lake in the
southern end of the unit. These historic structures are clearly visible along the southeastern
boundary and across Shirk Lake and the surrounding dry lakebed.
In addition, there are about 15 miles of primitive motorized routes that intrude into and across
the unit, along with about 0.4 miles of reclaiming routes, 4 water developments, and 8 miles of
pasture division fence (Map 2). All of these features are noticeable from close proximity, but
with the exception of the man-made structures in the southern corner of the unit, the overall size
of the unit and the juxtaposition of the man-made features leave this unit in generally natural
condition to the casual observer.
For these reasons, the BLM ID team concluded that the unit is predominantly in a natural

Summarize any known primary reasons for prior inventory findings listed in this table:
In 1980, the unit was described as a dry lakebed with some low hills in the northeastern corner. Guano
Lake sits along the western portion of the unit and is approximately four miles long and one-half mile
wide. The remainder of the unit was vegetated with sagebrush. Road intrusions had a major impact in the
northeast of the unit. There were 5.5 miles of ways and a well noted inside the unit. Approximately 50%
of the unit was affected by the works of man. The remaining portion of the unit was generally in a natural
condition. The unit did not offer an outstanding opportunity for solitude due to the generally flat terrain,
low vegetative cover, and relatively small size leaving one exposed to others inside the unit. The flat
expanses of the unit did not provide any outstanding primitive and unconfined recreation opportunities.
There was some potential noted for presence of archaeological values, but none were documented at the
time.

Yes __X__
No _____
Between 2008 and 2012, members of BLM’s staff conducted field inventory in the area as part
of a process to update both its road and wilderness inventories. This included driving and
collecting photo documentation of the routes and human disturbances in the area. Using 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 determinations in 2012.
Initially, the BLM ID team determined that the unit is bounded by BLM Road 6106-00 on the
west, 6106-B0, 6176-N0, and private land on the north, 6176-00 on the east, and both private and
state lands on the south (Map 2). Upon further review of the natural character of the unit, the ID
team revised the unit boundary by using a fence and primitive motorized route (interim number
6106-BE) to exclude an area in the northeast portion of the unit with a relatively high density of
unnatural features (see the discussion of natural condition below). Refer to the route analysis
forms, photos, photo logs, and BLM ID team meeting notes in the wilderness inventory file for
additional supporting information regarding these boundary determinations. 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 inventory unit is located about 20 miles east of Adel, Oregon, near Hart Mountain National
Antelope Refuge (Map 1). The unit currently contains about 15,035 acres of public land. The
unit size and shape have changed since the original inventory was completed in 1980, but the
overall topography and vegetation have not changed substantially. The unit is extremely flat and
vegetation consists of low-growing grasses and sagebrush.
(2) Is the unit in a natural condition? Yes _X_
No __ __
N/A _____
The historic Guano Lake unit (1-135) was found to have about 50% in natural and 50% in
unnatural condition in 1980. Since the initial inventory was completed, a few of the motorized
routes across the center of the unit have reclaimed.
As noted in 1980, primitive road intrusions continue to have a negative effect on natural
character in the northeast portion of the historic unit. In addition, several miles of fence, private
lands, and 3 water developments were also noted in this area, which negatively affect natural
character. For this reason, the BLM ID team used a fenceline and interim route number 6106-BE
as the northeastern boundary for the current, which effectively excluded these unnatural features
from the unit.
2
Today, there are about 9.7 miles of primitive motorized routes that intrude into and across the
unit. Many of these routes are not substantially noticeable, and may disappear seasonally during
wet periods. There are also about 6.5 miles of reclaiming routes, 6 water developments, and 1.6
miles of pasture division fence. All of these features are substantially noticeable from close
proximity, but the overall size of the unit and the juxtaposition of the man-made features (many
are located near the unit boundary) leave most of this unit in a generally natural condition as
viewed by the casual observer.
For these reasons, the BLM ID team concluded that the current unit is predominantly in a natural
condition where the works of man are substantially unnoticeable. The team also determined that
the northeastern portion was not only in an unnatural condition, but also failed to meet the size
criteria.
(3) Does the unit have outstanding opportunities for solitude? Yes___ No _X_ N/A ____
The unit continues to offer little opportunity for solitude due to the flat topography, lack of tall
vegetative screening, smaller size, and narrow shape. The low rolling terrain noted in the
northeast end of the historic unit are no longer located within the current unit and, therefore, do
not contribute to opportunities for solitude.
For these reasons, the BLM ID team determined that solitude opportunities within the Guano
Lake inventory unit have not improved since 1980 and, therefore, the unit continues to lack
outstanding opportunities for solitude.
(4) Does the unit have outstanding opportunities for primitive and unconfined recreation?
N/A _____
Yes _____
No __X__
While the ID team noted there is some potential for hiking and wildlife viewing, the flat expanses of the
unit and smaller unit size continue to limit these opportunities. In addition, these opportunities are
similar to those available on other public lands in the general area. The unit does not offer either
a single unique primitive recreational opportunity or a diversity of primitive recreation
opportunities.
For these reasons, the BLM ID team determined that the primitive recreation opportunities
within the Guano Lake unit have not improved since 1980, and therefore, the inventory unit
continues to lack an outstanding opportunity for primitive and unconfined recreation.
(5) Does the unit have supplemental values? Yes _____ No _ __
NA _X___
The BLM ID team did not evaluate supplemental values, as the unit failed to meet the minimum
wilderness criteria.

Summarize any known primary reasons for prior inventory findings listed in this table:
In 1980, unit 1-134 was broken into 2 sub-units along Road 6106-B0. Sub-unit 1-134A contained
approximately 3,360 acres and was not evaluated further. Sub-unit 1-134B consisted of about 22,080
acres that was described as a generally flat with some broken basalt rims and large flats at different
elevations along with some smaller hills. The major topographic feature is Lone Grave Butte which rises
to 6,150 feet in elevation. This unit is long and narrow and rise gradually in elevation from south to
north. Vegetation communities were primarily sagebrush. The unit contained approximately 13 miles of
vehicle ways and a two mile fenceline up the south slope of Long Grave Butte, but overall was in a
natural condition. The somewhat broken terrain provided some opportunity to find solitude. However,
the broad expanses between elevation changes left one exposed to others. For this reason, solitude
opportunities were no found to be outstanding. The unit was noted as providing big game hunting and
1
winter trapping, but these were associated with motorized vehicle access. The unit provided some
opportunity for hiking and wildlife observation, but these were not found to be outstanding. No
supplemental values were noted.
In 1980, unit 1-135 was described as a dry lakebed with some low hills in the northeastern corner. Guano
Lake was noted along the western portion of the unit and was approximately four miles long and one-half
mile wide. The remainder of the unit was vegetated with sagebrush. Road intrusions had a major impact
in the northeast of the unit. There were 5.5 miles of ways and a well noted inside the unit.
Approximately 50% of the unit was affected by the works of man. The remaining portion of the unit was
generally in a natural condition. The unit did not offer an outstanding opportunity for solitude due to the
generally flat terrain, low vegetative cover, and relatively small size leaving one exposed to others inside
the unit. The flat expanses of the unit did not provide any outstanding primitive and unconfined
recreation opportunities. There was some potential noted for presence of archaeological values, but none
were documented at the time.

DOCUMENTATION OF CURRENT WILDERNESS INVENTORY CONDITIONS
a. Unit Number/Name: Hart Mountain Southeast Area – Small Units <5,000 Acres
(1) Is the unit of sufficient size? Yes
No
X
In 2005, the BLM received a citizen proposal from the Oregon Natural Desert Association
(ONDA) for a 424,570-acre area they referred to as Hart Mountain 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 update for this area. The photos submitted by ONDA were taken in 2004. They
identified this large area as having no interior routes which met the BLM wilderness inventory
definition of a road (see Map, p. 96 of ONDA 2005).
Between 2008 and 2012, members of BLM’s staff conducted field inventory in the area as part
of a process to update both its road and wilderness inventories and to gather additional
information to supplement ONDA’s wilderness information. This included driving and
collecting photo documentation of the 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
determinations in 2012.
The BLM ID team determined that several of the routes ONDA identified as “ways” are, in fact,
roads defining inventory unit boundaries. For this reason, the BLM found that the proposed
WSA is not one large roadless unit, but is comprised of several smaller inventory units, 3 of
which met the size criteria and 6 others that did not (Map 2). (The 3 inventory units which met
the size criteria have been evaluated separately).
This evaluation focuses on the 6 units which the BLM ID team identified were less than 5,000
acres in size and did not meet any of the exceptions to the size criteria. These units are bounded
2
by Highway 140 right-of-way, BLM Roads 6106-00, 6106-A0, 6106-B0, 6176-00, 6176-K0,
6106-L0, 6176-N0, and interim numbered roads 6176-KA, and private and state lands (Map 2).
Refer to the route analysis forms, photos, photo logs, and BLM ID team meeting notes in the
wilderness inventory file for additional supporting information regarding these boundary
determinations. 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 inventory units (numbered OR-015-0000) are comprised of BLM-administered lands located
approximately 20 miles east of the town of Adel, Oregon (Maps 1 and 2). The topography can
be described as flat lakebeds or rolling hills with mixed rims canyons. The dominant vegetation
in the area is predominantly sagebrush and grasses.
(2) Is the unit in a natural condition? Yes
No _____ N/A
X
The current natural character of these units was not evaluated because they failed to meet the
minimum size requirement.
(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
N/A___X_____
The current opportunities for solitude within these units were not evaluated because they failed
to meet the minimum size requirement.
(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
N/A___X_____
The current opportunities for primitive and unconfined recreation within these units were not
evaluated because the units failed to meet the minimum size requirement.
(5) Does the unit have supplemental values? Yes
No
N/A___X_____
Supplemental value was not evaluated within these units because they failed to meet the size
criteria.
