Pearson 1970 Went to the park guard's for dinner (Horacio & Silvia) with Carlos his cousin) their friends [illegible] and Sir J. Delufo. Put out about 35 museum specials sorted with cornmeal along a fence of huge loop at edge of a field and along two small brooks through eucalyptus/cypress forest with lots of fallen limbs but otherwise rather open floor. Oct. 26 Night calm & clear, morning not cold, my traps lost +3 12 Orzyopsis, 1 also elin., 1 also longi. Anita's held 9 Oryz., 2 also longi, 1 also elin., and 1 Notomyia valdiv. Day mostly cloudy. Steel trap in the chicken yard caught an adult, pregnant (9 emb.) Rattus norvegicus. When I went to sort my line at 7:30 p.m. I found 3 more Oryz. and 1 also longi. I must have missed these first 3 traps in my line this morning; a dead and a 9 Oryz. in same snap trap! At 5 p.m. we put traps at the waterfall about 1 km above the park guard house. The falls are spectacular, about 100-150 ft., much spray coats the steep canyon walls mosses etc., including the only ferns that I have seen here. I put about 20 snap traps and Anita put 15 snap and 15 Sherman in slightly drier habitat downstream. There is the remains of an old paddlewheel sawmill at the park guard house, remains of irrigation ditches below the falls, and old-peg-sloped eucalyptus, so I think most of this area was clear 50 yrs ago and in our second growth.
