| Bed Rock Mortars along South Pasture Trail |
 |
| Rush Ranch's blacksmith shop |
The
South Pasture Trail mostly traverses
Rush Ranch grassland east of the
Suisun Marsh. The trail begins south of the barn between the
blacksmith shop and the antique farm equipment. First, you will pass an
Aermotor Windmill (702 Model); or, maybe, you want to spend some time at the windmill and read about its history and technical details. This farm windmill was made by Aeromotor, a manufacturer in Kansas in 1932. The structure is moderate in size, compared to a tall tower of a modern wind turbine. It actually is a
windpump, employed to fill the ranch's stock water tanks. This windpump converts the rotary motion generated by the wind-blown wheel of steel blades into a steady up and down pumping stroke. An informative panel on-site explains: “The piston-pump cylinder pulls the water out of the well and pushes it through the distribution lines to the stock water tanks. The modern water-pumping windmill has gone through very little evolution in the past century and serves as a testament to its perfect design.”

As you continue southbound on the trail, you will cross
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.
