Greene, H. 1982 7 May Left Berkeley ~1030h w/ David Sundale (Zeligh U.), Kurt Schwerke, and George Schwerke. Arrived at Darwin Falls parking lot ~2240, after dinner in Olancho and a beautiful full-moon drive. Got 2 Crotalus scarates in the Owens Valley at 2057 & 2124 hz, after moon was up and before it was really bright. Very windy at times. 8 May Darwin Falls Canyon, Inyo County, California Up at 0700. From ~0800-1030 we split up and looked for lizards on the canyon floor & walls, N. of the parking area. Not many lizards out, but we got 3 Sauracalus obsesus, 1 Callisaurs, and 1 Cnemidophorus. I missed a Uta and Kurt saw a Grotaphytus vicinetores. Walked to the falls and back, leaving ~1330-1400. Saw a kingfisher, a little blue heron, and a hawk w/ a lizard or snake in its talons. Saw numerous Cnemidophorus and 1 Bago boraes in the lush part of the canyon. Was surprised to see a large section dry because of a diversion ditch carrying water to a pipe. Irona Road, 1.0 mi. N. jet w/ Hwy 395, Found an adult live Crotalus mitchelli on the road at 1551 hz. It rattled. No rocks nearby - creosote shrub- but hills on
