Cori, Bor 1973 Journal Kyle Canyon, 5000', Clark Co., Nev. july 19 Turned west and looked for a topping site. We made camp at Kyle Cyn. Compound, Togobee Rthl; Forest, 7000', and drove down the canyon. at 4500', The habitat was creosote - querc - blackbrush mix. I elected to drive up the canyon to the road leading to geopenie Spring, here we climbed onto a mesa along the road where the habitat was blackbrush, Joshua Tree, yucca, and Artrplex mixed, with some Purple sage. We set our traps 1/2 mi. N. Hwy 39. Rodent activity was low but present. We set 100 live traps, in lines of 12, 4 each side of the road & baited with wild bird mix. The habitat changes to canyon- juniper woodland at 5700', and then to ponderosa Pine - chapbel oak forest at 7000'. Temperature moderate low 80's at 7:00 AM. It is too dark to set traps effectively at 9:30 Vox.
