Salt 1947 Journal Little Morongo Valley, Elev. 1500', Riverside Co., Calif. creosote bush and cholla. Mostly it is bare decomposing granite which breaks into large boulders. Hillsides are very steep and show no signs of change in foliage type with increase in elevation. I walked up one small tributary canyon a short way. The walls were very steep, almost bare rock, and at the bottom met to form a narrow floor about a yard wide filled with sand. The weather was clear, with a slight tight haze. Air temperature at noon was about 28° C. Walked back and forth over the sand on the table where our camp was. Collected three Callisaurus draconoides in an area of about 500 sq yds. Saw about 3 more which gives an idea of density. (Data for specimens in catalogue of R.C. Stedins) Also collected a Cnemidophorus tessellatus. (data same place as above) and saw numerous Uta & stansburiana. Saw an antelope ground squirrel. Following birds were present: Desert Sparrow, Bullock Oriole, Ash-throated Flycatcher, Costa Hummer, Black-throated Gray Warbler, Pileolates Warbler, Screech Owl, Horned Owl.
