E.L. Karlstrom 1954 Rana boylei (3) July 23 merced River at base of El Capitan, 3950 ft., Yosemite Valley, Mariposa Co., Calif. at 11:15 A.M. (D.S.) I drewed one adult frog at edge of river. It was beneath a clump of willows and immediately swum to deeper water when I tried to approach it. Water depth 5 feet out from the bank 4 feet. This is first yellow-legged frog I have seen in the valley proper. I recall Richard Zweifel mentioning that he did not see or hear of them from the Valley. I check Y.N.H.A. collection at museum. One R. boylei (2) serial # 268 from Fern Spring, Yos. Natl. Park, 4000 ft. I am not certain where this locality is, but no other definite Valley localities listed for R. boylei boylei. Bullfrogs apparently are established in a pool at the Ahwahnee Hotel. Could there be escapes to the River? * Note. Later "reliable" information from owner of pair of bullfrogs: single adult -> bullfrog. Party worker at hotel ostensibly raising bullfrog for Calaveras competition, and it is receiving training in Ahwahnee pool. My informant was clear-tongued but "feeling good" at beach party in August given by Ahwahnee chef Pearson for championship softball team. The punch (vodka+) was terrific!
