E.L. Karlstens 1954 Bulter cornus (14) may 27 0.2 mi. NW Kaiser Pass Summit, Fresno Co., Calif. While I was recording 11:48 A.M. I saw a large adult toad climbing across a snow drift 4 5' x 10'. It took her about 2 minutes to cover the 40 feet, and it was conical to watch from my crowded position her body aggering and disappering in the pockets of the very glazed surface. I caught her just as she ploged down into water. Her cloacal temp. 19 °C., surface of snow 3 2/3 ° C. Water into which she had dugged and remained 1/2 minute was 18° C. Apparently she had climbed out from pool at other end of snow patch. Temp there, also in about 3" water was 18.8° C. Earlier, about 11:30, I had seen an adult toad walk from shallow run-off pool to a deadfall 2 1/2' thick log and move under its edge. Log buried 3-4" deep in meadow sumps. At 12 noon I checked spot where I had seen the toad. Numerous (8) deperesive digs enough to house adult toads were (had been turned?) along but 7 feet of this 36' long deadfall. Temp. in one "burrow" 5.8° at 12:05 P.M. Oh, now I see the head of a toad. He lies in shade under log, can retract whole body as I move for him. Seems curious and comes out faster. Cloacal temp. 9.1° C. depression 7.8° C. Such retreat would offer excellent night - time refuge when meadow freezes. At 12:05 I hear a dead on calling toads (nothing disturbs them for long now!) My mike is set up 60' W of the NE pie first edge of the meadow, I
