Emigrant Lakes to Dorothy Lake, Emigrant Wilderness and
Yosemite National Park, Tuolumne Co., CA
Aug. 21 I hiked back from Emigrant Meadow to Drizzly Meadow,
stopping at the pond I visited yesterday, roughly 0.75 km southwest
of Emigrant Pass and just south of the trail to Drizzly Meadow,
to collect two Bufo tadpoles (SMR 70+71) (38.19543°N,
119.63842°W [WGS84, 6m acc.], 2944m elev.). I didn't collect any
Rana tadpoles but saw some. I took the higher elevation trail
from Drizzly Meadow over Bond Pass and passed through open
glassy pine forest that looked like good lizard habitat, but saw
none. I spent the afternoon propping the toads; SMR 69 died on
the trip back and was somewhat dried up. After finishing, I
walked with [illegible] Kim up to the unnamed lake above Dorothy
Lake to the SE. At the east end of the lake we saw a small
pond with I. regilla tadpoles (38.16934°N, 119.58521°W
[WGS84, 5m acc.], 2887m elev.), but I didn't have anything to
collect one in. We walked up the slope to the southeast, near
Forsyth Peaks, to look at some seeps (38.16661°N, 119.58513°W
[WGS84 7m acc.], 2969m elev.). There were some vegetated seeps
and a steady trickle of water over granite that looked good for
salamanders, but there weren't many rocks to flip and we only
searched for about 10 min. The best habitat, flat rocks lying on
the granite in front of services, was dry; it seems like this
would be an excellent site for salamanders earlier in the year.
There were some small seeps to the west that we didn't check.
The day was warm and clear, with clouds in the late afternoon.
