The Middle Fork is a tributary of the Salmon River, which is the main tributary of the Snake River, which in turn is the main tributary to the Columbia River. The Middle Fork is one hundred miles of whitewater. The nearest town is Stanley, Idaho. The Middle Fork's elevation starts at 7,000 feet (2,100 m) above sea level and drops down to 3,900 feet (1,200 m). Bear Valley Creek and Marsh Creek converge to form the Middle Fork. The Middle Fork has around a hundred tributaries; some of the bigger tributaries are Rapid River, Loon Creek and Camas Creek. These three tributaries range from 20 to 25 miles (32 to 40 km) long. The Middle Fork flows through 2,500 square miles (6,500 km2) of rugged terrain known as the Salmon River Mountains, in which there are peaks that reach as high as 10,000 feet (3,000 m) (Midmore 1–2).
