Salt 1947 Journal 3/2 mi E., 1/2 mi N, McChesney mtn, 1900 ft, San Luis Obispo Co, Calif. Sept.4 (cont.) The walls were so close together we had to straddle the pool to get over it. Walked up main stream bed till we came to very high walled portion, the site of a waterfall during wet times of year. There was a long pool 30 feet long, 8 feet wide, and about 4 feet deep at base of "waterfall". Walls of canyon were almost sheer so we back tracked and started up side. Heard Canyon Wrens, saw Black Phoebe, and Arkansas Goldfinch. Reached top of hill by going through manzanita & scrub oak. On top found low Adenostoma and Erodium where fire had been. Saw rodent holes and apparent dust bath sites in this low chaparral. Saw Sceloporus on rocks on all of trip. Not only small ones but large (up to 5") as well. Temperature was about 90° F. at 10 A.M. Skinned the rest of the day. Forgot to mention Western Tanager which I shot in oaks west of camp while checking traps in morning. Shot a Pipistrellus in the evening. Storer and Dr. Miller collected a Screech Owl by camp.
