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.
