This square perched boulder is next to a large propped boulder shaped like an inverted triangle (1/8/14). Perhaps this table-like surface was once a work site. At the center of this corner and close to a stream stands this large propped boulder.
This area has been altered by farming, as indicated by a building foundation.
However, a nearby small hill overlooking a stream would have been a good camp site. This may have been the residential part of the corner.
Further along the stream is this large propped boulder on another small hill. I took this picture weeks ago, before the snow started falling.
There is a boulder with a deep concavity by the stream.
This looks like a grinding slick. Perhaps this was once the women's work area where they crushed acorns and soaked them in the stream to remove the tannins.
This is why I park on the road. I nearly lost a boot in this mud!
