5.5.3 Tuolumne Table Mountain

Finds from mine shafts can be dated more securely than those from hydraulic mines and surface deposits of gravel. Many shafts were sunk at Table Mountain in Tuolumne County. Whitney and others reported that miners found stone tools and human bones (Section 6.2.6) there, in the gold-bearing gravels sealed beneath thick layers of a volcanic material called latite. In many cases, the mine shafts extended horizontally for hundreds of feet beneath the latite cap at a depth of over 100 feet below the latite (Figure 5.12).

Tuolumne Table Mountain was created by a massive latite flow which moved down the Cataract Channel, a Miocene course of the Stanislaus River, forcing the river into a new channel. According to R. M. Norris (1976, p. 43), the latite lava cap is 9 million years old and is 300 feet thick in the vicinity of the town of Sonora. Slemmons (1966, p. 200) gave dates for the latite cap and underlying strata at Tuolumne Table Mountain (Table 5.3).

Discoveries from the auriferous gravels just above the bedrock are probably 33.2 to 55 million years old, but discoveries from auriferous gravels whose positions are not specified may be anywhere from 9 to 55 million years old.
