Rana muscosa Cathedral Creek, Yosemite Nat'l Park, Tuolumne Co., Calif. more extensive tests (or something) but didn't think of it 'til later. 1st indiv. found sitting on rocky/gravelly sand bar to grassy banks; sunny. 2nd indiv. spotted ~ 5' from where found juvenile. He was scared off. The bark's went under a log (small which had fallen across the stream & apparently hid in some thick "slimy" looking algal(?) growth on the bottom. We return ~ 1/2 hr later & found him sitting submerged in the sand ~ 1 ft' upstream from the log. This time we saw where he went & was able to capture him. scared over here & captured. depth 20 algal(?) growth also quite a grassy bank) 3rd indiv. found farther downstream sitting in the bottom of a sunny 6-12 in. deep pool.
