Bob’s Mortar


Bob’s Mortar
75 bedrock mortars, including 9 in a satelilte site about 100 ft. away
Elevation 1380 ft.

This site was named for the first mortar Bob discovered on his own. It is a single large bowl on a rock right beside the trail. Below the rock a small perennial spring or seep dribbles water into a creek that flows down to the Round Valley Village.

Across the trail from Bob’s Mortar lie 74 mortars, 25 on one rock, including 9 mortars (5 in a basin) about 100 ft. away from the others.

Bob listens to water flowing below his eponymous mortar. This huge bowl is unlike any mortar at this site. Did it have some special significance?


Here’s the little creeklet that flows all year round from below Bob’s Mortar. Note the native bunch grasss growing in its water course.
