30+ bedrock mortars
Elevation 663 ft.
Thanks to Adrian for turning us on to this site above the Club Moto dirt bike track.
The mortars here sit on a little knob at the mouth of the Altamont Pass. Bob enjoys the spectacular view over the Livermore Valley.
Many of the mortars here are huge and weathered. The sandstone is not as well-cemented as that found in Volvon territory.
