"A lake, decidedly, is more than a mere
body of water;
Contained by sand, moved by wind,
wave, and ice.
Rather, it defines, in time and space,
myriad environments
That offer myriad viewpoints to all who
frequent it."

• Archimedes described a numbering system
for the grains of sand in the universe (1063)
• Myriad: 104 = 10,000
• (~ summer inhabitants of Crystal Lake)
• Myriad myriad: 108 = 100,000,000

• Up to 30–45 meters (100–150 ft) tall, and 3 meters
(10 ft) in diameter
• Related to European Sweet Chestnut (C. sativa);
Chinese Chestnut (C. mollissima); and Japanese
Chestnut (C. crenata)

Uses
•
•
•
•
Natural ecological sustainability
Urban landscaping
Food for wildlife, livestock, and humans
Fine woodwork, furniture, musical
instruments.
• Charcoal for use by blacksmiths
• Construction, fencing, boxes, barrels, railroad
ties, telegraph poles, mine timbers.
(Resistant to rot).
• Tannins (from bark and wood) extracted for
leather tanning industry
Humans & Chestnuts
•
“The fruit is very nutritious, energising,
remineralising, a tonic for muscles, nerves and
veinous system, anti-anemic, antiseptic and
stomachic. It is recommended to convalescents.”
-- Dr Jean Valnet, Traitement des maladies par
les légumes, les fruits et les céréales, 1964.

Not native to NW Lower Michigan
Planted by early settlers for nut crop
~15,000 surviving trees, 271 sites (1970’s)
A grove of several thousand chestnut trees
planted ~ 1910 on the old Rogers farm at
Chimney Corners ( SE ¼ Sect. 35, T27N,
R16W) at the top of the Point Betsie Moraine,
a massive 300-foot glacial ridge which flanks
the north shore of Crystal Lake. The stand,
located at the south edge of an open field
once used as an orchard, is bordered on the
south and west by a beech-maple woodland.
Thompson, P(aul) W., A Unique American Chestnut Grove, Mich. Acad. 1, 173-8 (1969).
Demise - Chestnut Blight
• Worst disaster in forest history.
• Introduced into North America in 1904 from imported
Asiatic chestnut trees. Reached MI by 1916.
• Cause: Asian bark fungus (Cryphonectria parasitica)
• Symptoms: bark cankers, wilting of distal foliage,
and formation of epicormic sprouts.
• Sticky orange tendrils on epidermis; within the xylem
vessels become clogged.
• New shoots often sprout from the roots when the
main stem dies, but rarely grow more than 6 meters
(20 ft) before blight returns.
Whether the Blight?
“Will the blight end the chestnut?
The farmers rather guess not.
It keeps smoldering at the
roots
And sending up new
shoots
Till another
parasite
Shall
come to end the blight.
-- Robert Frost, ~ 1930’s
The American Chestnut Foundation
• The goal of TACF is to restore the
American chestnut tree to its native
range within the woodlands of the
eastern United States, using a scientific
research and breeding program
developed by its founders.

and Processing Sweet Chestnuts
• About sweet chestnuts
• Products: fresh chestnuts, peeled frozen
chestnuts, chestnut slices, chestnut flour
Chestnut recipes
• Scheduled chestnut roastings

Resurrection - Genetics
• Pruning and sprays ineffective due to re-infection.
• Selection of hypovirulent (less-susceptible) trees
somewhat successful.
• Introduction into the American chestnut the
genetic material responsible for blight resistance
of the Chinese tree, but also preserve the genetic
heritage of the American species.
• 15/16 American chestnut : 1/16 Chinese chestnut.
