Sept. 7. Jamie, Jamie N., McChesney Mt., 1900 ft., San Luis Obispo Co., California come down the opposite slope but keeping a good distance away & up canyon the Valley Zica I called from behind me & also seemed to be going up canyon. After a few minutes I saw 4 or 5 Quad presumably Mountain going up the top side of the canyon across & up canyon from me. Took a long shot at the last one - 9's & missed. Collected 20 traps at lower set of pools & got 3 P. boylii there. Returned to camp & skinned that the Peromyscus. The fifth was a D? or a bobbed tail. About 2:30 pm went down main canyon via the small canyon which runs by the cabins. In the small canyon there is a waterfall (in the wet season) which cuts through a wall of Conglomerate here I found Pityrogramma, Cheilanthes californica, C. corvillii, Pellaea endivesensis?, Selaginella bigelovii & Pellaea humeralis. In the main canyon I passed a fairly large pool (12-15 ft long) into which 5 Rana canorus(?) jumped. In the water was a small, slimy, stumpy snake which I struck & apparently missed as it disappeared. Down canyon away I collected a Purple G. Sparrow. Finally reached the waterfall with a pool above & one below which Bill & Paul found several days ago. Here I shot 2 Ravens (one of a pair which was circling over the canyon). The bird flew off down canyon on with the second, shortly afterwards a single raven came back & circled over me. This made me wonder whether I had hit the other one but I couldn't go
