Jeff’s Pestles


Jeff’s Pestles
One bedrock mortar and five pestles near a spring northeast of Mission Peak.
Elevation 1714 ft.

Another one of Jeff’s amazing finds. Please do not remove any of these pestles. Leave them for others to enjoy.

Pestles come in various shapes and sizes. Not all are flattened or tapered cylinders.
