July 1
Yesterday I drove from Bariboy up to Sonora Pass. I offloaded the
data from my logger at the 9000 ft sign onto the shuttle at 3:50 PM.
I searched in the area below the logger near the stream where there
were some mussel cracks with seepage and saw 1 adult female (SP17),
1 subadult (SP18) and 4 juvenile I. platycephalus. I got dorsal and
ventral swabs from SP17 & 18. I drove to Virginia Lakes and stopped
at Sardine Falls on McKay Creek, on the E side of Sonora Pass on the way.
I searched a seep area next to the falls and a little of the spray
zone for ~30 min (1445-1815) but saw nothing. The habitat looked
perfect, and Chris Fitchell found salamanders here last year.
On the morning I hiked west from Virginia Lakes looking for
seep zones. I made it as far as a small lake past Corney Lake
(38.84-863°N, 119.28121°W [WGS84, 13 max], 3158 m elev.). But
could see no suitable habitat, even using my binoculars. I left, drove
to Convict Lake, and hiked up the Convict Creek trail to my data
logger. The creek was extremely high and only ~10m of habitat
was exposed. I searched it from 1400-1445 and found 7 juvenile
salamanders, as well as the following ones that I swabbed (dorsal/ventral):
Swab # Age/Sex Photo Swab # Age/Sex Photo
CC17 subadult 1030018 CC20 subadult 1030024
CC18 subadult 1030019 CE21 adult ♀ 1030030
CC19 subadult 1030020
I also saw 2 subadults that escaped. I offloaded my data logger at 1516
and then pulled it out and took it with me. The day was sunny
and warm, in the 80s.
