Thunder River is a river entirely within the Grand Canyon National Park. It flows southeast from its source near the North Rim of the canyon to Tapeats Creek. The 0.5-mile-long (0.80 km) river is one of the shortest in the United States, and drops approximately 1,200 feet (370 m) over a series of waterfalls, making it the steepest river in the country. It is also a rare instance where a river is a tributary of a creek.
