Nature Notes From Crater Lake
Volume 4, No. 1, July 1931
A Challenge
By Frank Solinsky, Park Ranger
It is the ambition of most persons and
corporations to hold a distinctive record of one kind or another. Nature
has amply provided Crater Lake National Park with abundant material
which, we believe, surpasses any similar phenomena to be found
elsewhere. To continue in such a braggart tone is not congruent with the
policy of the Park Service. Therefore, with an assumed modesty, we make
public the facts concerning a gigantic tree.
This tree, a white pine (Pinus
monticolae), stands in the east slope of the Middle Fork of Annie
Creek. Measurements were taken in accordance with the Spaulding rule as
provided in their log tables and revealed the following figures:
The circumference, breast height -
28 ft. 2 in.
The total height - 140 ft.
The tree is probably about 1,000 years old.
The Middle Fork, as do the rest of the
creeks in the park, runs through a deep water and wind eroded canyon.
The great age of this tree provides an unusual opportunity for the study
of this erosion. The roots of the tree are well covered by soil and
there is no indication of ground creep. On the other side of the canyon,
we find trees in various stages of subversion. Some have toppled down
into the creek below while others, with their roots exposed, have the
appearance of standing on stilts. The curvature of some of these trees
indicates the presence of ground creep. The one-sided erosion of the
canyon can be attributed to the creek which runs under the west slope.
