To the south ? the trail, The slope is much less (~10-15%)
Further down the trail, the downward slope actually
increases (~ 150%). The plants change a bit (ponderose
juniper > bigger juniper). The spring which creates a
small (very small) ravine to south of the trail
runs year-long apparently (B. Lawrence, pers. comm.).
Overall, however, The habitat doesn't seem quite
very good for Bassariscus -- the northward slope
is far too great. The southward slope is manageable
but the hilltop < 50 m. above supports oak savannah
and residential habitats. Possible for ringtails, yet
unlikely. at trails base (Folsom Lake) we did
left along horstrail (north west) several hundred feet,
then turned north across the stream (via wooden bridge)
It is along this stream that ring tails are likely
to be found. The hillside slope ~ 30-55% from
oak woodland hilltops -- above the stream ~ 50 meters.
The hillsides are vegetated w/ live oaks -- in some places,
the habitat is more grassland than woodland. By and
