Here, a 2,200-foot-high flat-topped lava butte rises 1,000 feet above Banks Lake, the 31-mile-long irrigation reservoir filled with water from Lake Roosevelt by giant pumps and siphons. Water is distributed from the south end of the lake throughout the Columbia Basin. The state park has campsites, three cabins, a swimming area, and boat ramps. In summer it's popular with boaters and anglers, and in winter there's Nordic skiing, snowshoeing, and ice fishing.
