Clear Lake and Mt. Konocti from High Valley Ridge
Clear Lake from High Valley Ridge
This is a ridge that runs northwest for 12 miles between the north fork of Wolf Creek and Bartlett Springs Summit on the northeast side of Clear Lake.
The High Valley Road runs most of the length of the ridge from High Valley to the Bartlett Springs Road. The high point is towards the northwest end of the ridge less than 2 miles from Bartlett Springs Road. The road is well graded and passable to all cars albeit quite dusty in places during the dry season. This makes for a moderate but long walk up the road from High Valley or a short one from Barltlett Springs Rd. to outstanding views out over Clear Lake, Mt. Konocti and the Mayacamas Mountains beyond.
