Ronto, Sean 2005 Journal June 5 Half Dome and Vernal Falls, Yosemite National Park, Mariposa Co., CA Last night, cl stopped at Camp Curry with Chris Martinez, Solano and David Buckley. We hiked through the tent cabin area to a small stream and then followed the stream up to the granite wall at the south end of the camp, where it became a waterfall. There were lots of mossy cracks and plenty of wet areas, some with significant flow. cl found a juvenile Hydrotaphalus crawling on the wet granite wall at 10PM. The air temp was 82.0°F and 69.6% RH. We continued searching and found a Pseudacris, as well as another H. platycephalus which I collected (SMR 97: 37.73538°N, 119.57471°W [WGS84, 14m ase.], 2282m elev.). There seemed to be a lot of very suitable habitat near the waterfall, but the rock elsewhere was dry. The next morning (June 5), we hiked out from the Happy caves trailhead up the John Muir trial, starting at 10AM, and arrived at the top of Half Dome at 2:36PM. It was a sunny and clear day; and fairly warm (probably in the 80s). On top of Half Dome, there was a small snowfield in the center, with a lot of seepage and exfoliated granite rock on the NW side. David and cl searched and found 14 juvenile, 1 subadult and 5 adult H. platycephalus between 3 and 4:30PM (37.74507°N, 119.53387°W [WGS84, 7m ase.], 2622m elev.). cl got dorsal and ventral swabs of the adult and subadult salamanders, but the juveniles were all too small to swab. We searched all of the available habitat on this side of...
