Geocache Description:

Mount Ophir mine, mint and ghost town is a hidden piece of Mariposa History.

Mount Ophir is a ghost town in Mariposa County, California. It was founded during the California Gold Rush, and was the site of the first authorized gold stamping mill, or mint, in California. The stamping mill was built in 1850-51 by Moffat and Company, operating under the authority of Augustus Humbert, who had been appointed by President John Tyler to be the federal Assayer for California. The Mount Ophir Mint produced hexagonal gold slugs with a fifty-dollar denomination. Much of the coinage produced by the Mount Ophir Mint was later melted down into government ingots. By 1853 the mint was closed. The ruins of the mill are still visible. Mount Ophir during the early 1850s was a large camp, and stores and tents straggled along the main road for quite a distance. In 1854, Louis Trabucco purchased the stone-walled trading post in Mount Ophir, which was patronized by miners and packers. Its ruins now stand next to the foundation of a large two-store frame hotel built in 1852.

I have also heard that a bag of the $50.00 hexagonal gold pieces were lost while in route to San Francisco in the late 1800's. They have never been found.

Please DO NOT cross past the private property signs as the actual old ruins are on private property.

You are looking for a bison tube, so BYOP.
There is also a dollar bill for the FTF.

**Congratulations to Ham3 and FJ Jay for the FTF**
