The Salton Sea Basin feels almost alien. It lies where two enormous chunks of the Earth’s crust, the North American Plate and the Pacific Plate, are very slowly pushing past one another creating an enormous low spot in the land. It’s a big, flat gray desert ringed with high mountains that look pale in the distance. It’s hot and, deep underground, it is literally boiling.
