Bufo canorus (26)
may 30 Tuolumne mtns., 8600 ft., Yosemite National Park,
margosa cr., Calif. Down SW of campground about
1/2 mile. Air temp 8:01 p.m. (D.S.) 5.5°c. Water
temp. Shallow (max 4") 75 feet wide pool 14.6°c.
Meadows free of snow but a few scattered patches
around campground under pine canopy. Pines and
stems all high. The meadows are even less than
half greened out. New green grass averages 3" tall
but rises to 5-6". Very open meadows here cut
by many stem drainages. Lodgepole pine dominant
forest tree. Small conifers (single trunks) to 8"
height.

The melt-off water
matte of
dead leaves
here (1 1/2 miles SW of Tuolumne)
can form large shallow
pools up to 200 yards length. Clocked meadow
just W of store at Tuolumme. Nothing there.
Inigo Pass Ranger Station, 9950 ft., Tuolumne Co., Calif
Locality just W of Ranger Station still 1/4 covered
by snow to 2' thick. Meadows further W along
Road even more snow, 1/2 covered. Hygro (few) calling
but wary from under grass. Air temp 1" above
shiny grass 1.5°c. at 8:55 p.m. Water temp in
1 1/2" deep runoff 3.1°c. I listened for long
period and called canorus style. No crickets heard
or picked up with hardwire. Grasses just starting
to grow, less than 1" tall. Apparently this
area as well as Tuolumne not right now for
Bufo emergence. But why at Kaiser Pass under
