White Cloud campground, 11 mi. E Nevada City, Nevada Co., Calif. 4300 +/- ft.
4 April they were filling up with snow. I followed the
most recent set, which started under a fallen
incense cedar tree (leaves still green) about 75 m. SE
of the gate to the helipad. The squirrel may have gotten
onto the fallen tree via some nearby trees, thus leaving
no tracks. From here the squirrel (Douglas Squirrel judging
by the size) had gone roughly north, then circled around
to the west, coming about 20 m. E of the easternmost
pit toilet at the northern edge of the trip (where
it had evidently gone up into the trees for about 10m.)
then back south for about 118 m. (my paces) to a
clump of small incense cedars and large conifers. Two
of the incense Cedars had bark strewn beneath them
that was lightly covered with snow. Probably the
squirrel had torn it off. This finishing point was
about 35 m. WSW of the initial fallen tree.

The significant thing about this trip is that the
total straight-line distance from one end to
the other was over 100 m. There was one other
set of older tracks which were probably Gray
Squirrel tracks since they were larger. The track
of both species in soft snow seems to be similar.
