North of Imperial Valley lies the Salton Sea, a massive artificial lake located nearly 230 feet below sea. Fed by the area’s irrigation runoff, the lake’s high salinity averages just 15 feet deep. In many locations, low water levels have left long stretches of muddy shore exposed. Red Hill Marina, a county park on the southeast side of the sea, is in fact an island reached by causeway, but is currently surrounded by salt flats. Although I had planned to camp, I ended up only spending the afternoon. There’s no drinking water and I wasn’t carrying enough to last the few days I needed to rest. Before I left, the campground host topped off my water bottles and gave me a mango from his ice box, perhaps the best gift on a hot day.
