Comments: A note for those interested in climbing this area in spring 2011: the owner of the property at the corner where the gravel road turns to an unimproved dirt road (where drivers of non-4wd vehicles would park) said that a mountain lion had attacked a horse and killed a neighbor's dog last week (mid-March 2011). They also had seen new tracks in their yard this past weekend.
We decided that to head elsewhere, instead of always looking over our shoulders for a hungry mountain lion.
