Mormon Bar is in south-central Mariposa County about three miles south of the town of Mariposa. The area was placer-mined during the 1850s and 1860s, and, by 1870, the easily worked placers were largely exhausted. The area was mined again in the 1930s by dragline dredges, and there has been minor prospecting since. The total gold production for the district is estimated at 75,000 ounces. The deposits are in and adjacent to Mariposa Creek. The average depth of the mined gravels was about six feet.
