While miners worked nearby streams and veins for gold, George W. Coulter served their needs as merchant and hotel proprietor. His first store, established in 1850, was a tent stocked with merchandise hauled in by pack train. Coulter and the town which bears his name prospered, as Coulterville became the business and social capital of this area.
