Kosito, Dear 2006 Journal Aug. 15 Lyell Canyon, Yosemite National Park, Tuolumne Co., CA Yesterday, Dean Schivile and I hiked from Tuolumne Meadows to near the top of Lyell Canyon. We camped in the meadows area beneath the upper bowl of the canyon, where Emily Rudige, Jim Patton, Les Chow and Peggy Gransta and Carol Patton were working. Dean and I searched some seep habitat just above camp to the east at night for ~30 min but found nothing. Today, we walked to the head of the canyon and searched an extensive seep area that stretched from near the canyon floor to almost the top of the ridge, on the east side of the canyon (37.75174°N, 119.25568°W [WGS84, 8m acc.], 3452m elev.). The seeps looked like spectacular salamander habitat, with lots of wet areas and grass, moss, Minulus and other vegetation. We searched from 1000-1115 but found no Salamanders. We then searched another set of seeps at the very end of the canyon; these had almost no vegetation and looked like excellent habitat as well (37.74903°N, 119.26000°W [WGS84, 7m acc.], 3405m elev.). We searched from 1240- 1320 but found no salamanders. On both areas, but especially in those seeps, some areas were fragni; made me wonder if the cold nights had caused the salamanders to retreat into cracks. We returned to the first seep (E side at top of canyon) with Emily and one of the botanists' friends who hiked in yesterday and searched from 2045- 2200 without success. Emily and the other girl stayed in the bottom part of the seeps while Dean and I climbed nearly to the top. The day was mild and sunny, and the night was clear with lows below 0°C.
