Milligan is an abandoned settlement in San Bernardino County, California. Milligan is located at 34.2766750, -115.1702567 along Cadiz Road.
In the 1930s the Lucky Jim Mine near Milligan produced silver-copper ore which was shipped to Douglas, Arizona for smelting.[1] Located at a railroad siding of the Arizona and California Railroad, almost all traces of the settlement are now gone. An abandoned cemetery is in Milligan with 11 unmarked graves.
