Gymnogyps californianus April 14, 1946 Hopper Canyon, Calif. and moving about within 1/4 mile of these last 2, but they did not investigate us. Rising time - 9:50. Temp. 60° F. in blind, clear sky, light breeze. We pre pared to leave Big Cave area & collapsed the tent blind. The sand around the bathing pool was a solid interlaced mass of tracks for about 70 ft. from falls brink. Water was clear sweet & running over the falls. The primary which had been such a "toy" had about 1/3 of barbs cut, pulled or broken off, & the shaft was crushed in several places. Pulled up grass was evident on the green grassy spots near pool. At 10:50 when we were still at pool, one adult came over, curving & passed 150 ft above us, & an imm. (dark head) came in about 20 ft. over us as if to land, suddenly saw us & started flapping violently, & flew on up Condor Canyon & over the ridge to East Canyon. At 11:15 we were about 1/2 mile N. of Big Cave & we saw two imm. spiral in to land on or near Whitewash Ledge. Ed whistled loudly a number of times and after 3 min- uts the two took off & circled over the brush below us (we atop cliff) before heading toward North Slope. We continued on & arrived at car about 12:15. At the horse carcass then I saw ravens but no condor - a little later I saw 2 golden eagles being chased from the horse vicinity by ravens. & We lunched, then drove toward Parking Place. Met a group of 5+ picknickers at Old Cabin. Did Peyton had also been up to look
