Gymnogyps californianus June 19, 1946 Hopper Canyon, Calif. condors, circling & rising. They rose to 800' above the Rim, then scattered - at least 3 of these headed east & were over White Cliffs at 10:44. At 10:50 I was back at the road. Breeze light or absent. Then I drove to head of the tractor trail & hiked down to the creveldelawn Big Cove (arrived 12:00). Then on to Cada Falls (arrived 12:30). At 12:30 I saw 1 land in a green Po. near Flat Po. The falls was running a steady clear stream. This falls area has 3 main levels, each having a flat rock area & a good pool. The top pool is about 5x4'; shallow at the edges, but perhaps 20" at deepest (large rocks make bottom irregular). Where I saw 4-5 condors yesterday the wat. er was only 1-2" deep, then trickled through the more down the rock slope. About 20' below this was the center level having two pothole pools in a flat- tish space about 50' 30' long & 20' wide. The lower of these pools, about 1 ft. from cliff edge, so was where I saw condors brother drive yesterday. This pool was about 5x12' & perhaps 2' deep at most. The end where the condors bathed was about 6" deep with a sandy bottom. About 20' lower was the lowest low pool, a nearly circular one about 10' in diam. set on a flat place about 15' wide & 60' long. This flat was where I saw several condors running yea- terday. Some apparently flew about 100' S of this
