⛏️🌵 California's desert miners sometimes found an ingenious way to escape brutal heat: they went underground. Dugouts, mine tunnels and subterranean rooms could provide shelter where summer temperatures above ground became punishing. These weren't fantasy underground cities. They were practical spaces carved into the earth by people adapting to an extreme environment. California mining history wasn't only about what came out of the ground. Sometimes survival meant moving into it. #CaliforniaBuriedHistory #CaliforniaHistory #MojaveDesert #MiningHistory #HiddenCalifornia
