This map features the major watersheds of the Great Basin. None of them outlet to the sea, but instead end up in small lakes or just trickle off into nothing, often the result of being drained down to nothing for irrigation (or being diverted hundreds of miles away to permit Los Angeles to sustain a population far greater than its environment is capable of). The vast spaces between bothered me, visually, at first, but now I like how they give a sense of oases of population in the deserts.
