Zweifel Rana aurora cascadae 5200 ft Con Hollow, 1 mi. S, 5 mi. E Butte Meadows, Butte Co., Calif. Oct. 10, 1952 A sub-adult found resting on a branch 6" above the water (branch extending into stagnant water) beside an 8' x 5' x 1' deep level pool the main stream. The main stream is about 15' wide here, up to 2' deep and fast flowing. Time 1:30 PM. Sun behind cloud. White fir, lodgepole pine, yellow pine, incense cedar prominent. Sugar pine & red fir present. Caught another sub-adult in a pool in a small tributary stream a few yards from the main stream. Where it enters the main stream, the tributary is about 5' wide and 1' deep. I followed the tributary up a relatively steep slope about 50 yards to where it opened into a small (200 x 30 yds), lodgepole pine bordered meadow. The stream follows the edge of the meadow and averages 2' wide x 1' deep. Another small R. a. cascadae was cought in this stream. (indors cont.) All together, 12 were captured by Dr. Stabbins & myself. Of this number, only two was in the main stream, the rest in slow tributaries or in isolated pools.
