Start from the 175-Maple Shadows Rd intersection,Jog up Road to
No Tresp. Gate-easily circumvent,the trail is sometimes not easy to follow,go under a couple fallen trees,eventually do find the East Summit and very shortly after the Middle Summit and Cobb Mtn Peak,where I sign register,The West Summit peaking requires more perseverance,going through some brush but I do get there eventually in under 2 hours-Coming down though have major difficulties though-losing trail within a half mile after descending from the east summit-bushwhack my way all the way down until I finally hit a trail that leads to a private residence, but it is within a 100 yards of Highway 175 so rather luck-still a bit scary.
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.
