Took two tries to get to the county highpoint. The first time I was a little too cavalier and missed it by half a mile. Cobb Mtn is easy enough to find, but the West Rim is a bit tricky.
Hit bad fog on my 2001 try, but managed to visit summit. Went back in 2003 to do the Sonoma cohp with my wife. Nice hike, interesting area.
Hiked with pals Jeff and Alex. Started off normal enough but ran into over a foot of snow at the summit. Have to go back and get the Sonoma County high point on the west ridge.
