 The Humboldt Sink is a mostly dry lake bed just outside of Lovelock, Nevada. Along that dry lake bed, you'll find Lovelock Cave, a place humans have been using for thousands of years. Lovelock Cave is one of the oldest human-inhabited areas in northern Nevada. So there are stratas that have been excavated, and they have found human remains as well as other objects like duck decoys, the oldest in the world, in fact.
