The large section of a charcoal log which is now exhibited in the Information Building is apparently (Libbey, 1956) the same one as that which has previously (Anonymous, 1931:1) been referred to sugar pine (Pinus lambertiana Dougl.). Recent examination of material from this log has led Prof. D. W. Bensend (1956), Department of Forestry, Iowa State College, Ames, Iowa, to state that "one can say with a fair degree of certainty that it was ponderosa pine."
This identification, as well as the earlier one, is in line with the summary which Williams (1942:113) has provided of the species represented by various pieces of charred wood collected in the immediate vicinity of Mt. Mazama. Appreciation is expressed to Dr. Bensend for this contribution to our information concerning the natural history of the Crater Lake area.
