Salt 1947 Journal 1/2 mi E., 1/2 mi N., McChesney Mtn., 1900 ft., Sankuis Obispo Co., Calif. Sept. 5. Checked steel taps. No signs of activity at either set. Continued through the notch to main canyon of Martinez Canyon and started north south.. It was about 6:45 when I reached the canyon bottom. Sun was up and shining on east facing wall of canyon but not into bottom. Saw Bell Sparrows., Goldfinches, and Titmice at pool. Heard Heard Mountain Quail calling from dense covered west facing slope of canyon. Continued north along canyon bottom. Black Phoebes, Towhees of both kinds, Jays and chipmunks were active. After passing several other pools, reached the pool above the waterfall-site where Dehnel and I had to leave the canyon bottom on our hike north south yesterday. Found it to be about 25' long, 12' wide at widest place, and about 3' deep at one spot. There were a few spots of grass, a large clump of Canex, and a few Sycamore saplings.. Otherwise it was just a depression in the conglomerate rock. Found two small gray Hyla in the water there. They look like Hyla arenicolor to me but I may be over hoping. Started back to camp. Shot a Canyon Wren and near camp, a Rufous-crowned Sparrow in the juniper adenostoma on the burned over section near camp.
