TROCHET, J. 1992 Journal Cottonwood Creek, O'Neil Basin, 8 miles E. & 4 miles S. Deer's Pocket Peak, Bridger Mountains, Elko County, Nevada. Elevation 6500 ft. July 24-25 I left Caldwell at 10:30 and drove to NE Nevada via I-84 to US93 south through Twin Falls, Idaho, through Jackpot, Nevada to turnoff US. signs O'Neil Basin about 26 miles S. of jackpot on Hwy 93. I took a good gravel road NW approx 20 miles to Deemer Passel, where the road turns NNE. About 2 1/2 miles beyond the Deemer Ranch, the road crosses Cottonwood Creek. I camped here just downstream from the road crossing at a site which clearly had been similar used before. I set up the tent quickly after my 10:30 arrival under windy & threatening skies. Just to the N. Skies are clear! WNW NE 10-20 mph, Temp ~75°F, fairly humid. After tending to kids, I made a short foray downstream. A final supper after dark, to the musical accompaniment of several groups of crickets at greater & lesser distance from camp. On the morning of July 25 I made a foray 3/8 mile downstream & 3/4 mile upstream from camp. The stream drains cuts through basaltic rhyolite downstream and against a basaltic cliff upstream, 7 feet drainaged by big sagebrush. The stream itself is a meandering, slow-moving, small fish-containing water course, with several species of willows along the only large plants in the riparian zone. These are mostly continuous on two banks of the creek, mostly shrubs 5-10' tall, except 2 trees well upstream which are 20-22' tall and appeared to be black willows. Admixed with wilow is vibesprued is wild rose (Rosa) and a blue sp. More local are nettle, columbine, aster, & some other wildflowers. In the stream channel are rushes & sedges (former more common), and grasses of several types cover most of the flat lands adjacent to the stream below the level of the sagebrush feet. These flats are nicely adorned
