Groveland in Tuolumne County, California — The American West (Pacific Coastal)
The simplest form of the arrastra was a flat-bottomed drag stone place in a circular, rock-lined pit and connected to a center post by a long arm. With a horse, mule or person provided power at the other end of the arm, the stone dragged slowly around in a circle.
Ore place between the stone floor and drag stone was crushed into a coarse powder after which water and quicksilver were added. The resulting slurry was removed to sluices (troughs) were the gold was recovered.
Thanks to the efforts of the Stanislaus National Forest Groveland Ranger District, the title to the drag stone and all of the floor stones of this arrastra was transferred to the Groveland Yosemite Gateway Museum. It has been reconstructed by local volunteers.
