The Ancient Archway Found in a California Gold Mine Was Cut for Something Forty Feet Tall

In the autumn of 1897, a crew driving a drift from the bottom of a gold shaft, three hundred and twelve feet under Table Mountain in Tuolumne County, California, struck a face of rock that rang hollow. Behind it ran a passage walled in pale dressed stone. At its end stood an archway: two half-columns belted with three rings of stone, a single keystone, and forty feet two inches from the floor to the underside of that keystone. On the underside of the keystone, forty feet up, he found a polished hollow, worn like the head of a low cellar door. Nine days later an old Miwok man who cut wood for the mine came up to the collar of the shaft. He had not been underground. He told the surveyor what the old people said about the ridge, and he gave the place its name. Then he asked for one thing: that the opening be closed with stone, not with wood. The company closed it with timber. This documentary follows six records: a surveyor's notebook, the archway itself, an elder's words in 1897 and a pencilled note from 1913, a second engineer who went down in 1915, the echoes in the same belt of limestone, and a file that was never put together. They point at the same door. A door does not stand by itself. If this one opens downward, what is on the far side of the second? This documentary examines historical records, archaeological research, and Indigenous oral traditions. It presents documented findings alongside long-standing questions that remain open. Where accounts differ, both are presented. Nothing here is offered as a settled conclusion. #Miwok #CaliforniaHistory #TableMountain
