June 8 Horse Conell Under., 7645 ft Lewis North Forest, Fraser Co.
Early - air temp. 4:45 P.M. 26.1°C. 2" above dense
meadow (lilac bloomed) water temp. at A 21.8°C. Temp
at B 31.9°C. 1" below surface. A & B pools appear
to be separate, B about 2" higher. Tods in both are
disengaged, not very numerous (2-3 per foot square average)
and could represent two matizes. The flow is westward
in A while might account for wide disengagement of larvae.
Creek is meandering, varies from 3-4' to 25' across
with a half dozen "cascades" of a foot or two each.
Approximate flow is a yard in 2-3 seconds between
drops. Meadow at this point is about 200 yards E x W
and 250 N x S with continuing narrower necks to E
and South. Horse warms into the gorse-like while we
to 1/6-1/2" tall. Dodecatheon, Ranunculus scattered &
blooming. Asphare are half leaved out (leaves 1/2 full
size) lodgepole pine stands from all around to this
most open meadow but Jeffrey & dugor pines appear
amongst the lodgepole. Prior Wilby found more tods (same
stage) at C a shallow silty bottomed seepage flow
2-3" deep. Water temp. 20.2°C. Now may one
groups of tods found N of site C. Sink holes, ditch
like seepage flows have. Meadow boggy. One sink 12'x20'
and max. 8" deep so brown-stained tods badly can be seen.
There are larger (sample taken) and thicke. Water temp. 31.0°C.
at 5:20 P.M. Large Ithyla tods present in this yard D,
so far tods from 8-24 mm. Observed and no eggs.
Rana muscosa adults abundant along with yearling tods.
