North from Pinnacle Rock
This is an instant gratification peak like Moro Rock in Kings Canyon where a short walk-up yields panoramas that usually require an honest days work to earn.
The Bartlett Springs Road climbs dramatically winding up from the north end of Clear Lake into the heights of the Mendocino National Forest. It reaches an elevation 4,000' at Bartlett Springs Summit and continues on down over ridges to Indian Valley Reservoir for a total of 26 miles. The road passes below the southwest slope of Pinnacle Rock, the highest peak in the area.
The southeast slope is doable from the road but much of it is nasty scrub brush, loose crumbly rock and scree which makes the little drive though the forest from the north to within a stroll of the summit rocks a welcome alternative. Pinnacle Rock once had a fire lookout and there are rock steps leading up a short distance to the class 2 summit rocks which are much more solid than the rock below.
The views are quite outstanding for the minimal effort. North is hulking Goat and Snow Mountain, to the east Rupert Ridge, Evans Peak and Wolf Creek Ridge, to the south is Clear Lake with Mt. Konocti and Cobb Mtn. on the horizon. To the northwest is Windy Point and Horse Mtn. with the Mayacamas Range to the west beyond Clear Lake.
For the excellent views south and east go beyond Pinnacle Rock east on the road below it out about 1/4 mile to the open east shoulder.

The road continues about half a mile to where it goes up to the left through some trees to the stone steps going up to the summit rocks which are hidden from view on the approach.
It is a short walk of less than half mile with a few hundred foot gain.
You can drive all the way to below the summit rocks if this last part of the road which is rutted is suitable for your vehicle.
