Spring Ranch Creek and come to an overlook. Follow the path where a sign announces that the trail is maintained by the employees of Kiewit Infrastructure West Co. to get to the Bed Rock Mortars. Soon you will stand in front of the Grinding Rock used by local Patwin Indians for food grinding. What kind of diet did they grind on this rock? According to a panel next to the mortars, Patwin Indians may have ground dried meat, which they prepared from waterfowl and salmon they successfully trapped or speared. The Suisun Slough and its surrounding marshlands certainly must have been an excellent hunting ground.
While you are completing your South Pasture loop trail hike, you will find other points of interest described in the South Pasture Trail Guide hand-out available at the visitor center. While studying the objects next to the trail, don't miss the views of the nearby tidal march—Suisun Marsh—and Mount Diablo further south.
