The Buffalo Fork is a river that begins in the Teton Wilderness of Bridger-Teton National Forest in the state of Wyoming. The river has a north and south branch, both of which begin immediately west of the Continental Divide. Buffalo Fork travels southwest into Grand Teton National Park and empties into the Snake River adjacent to Moran, Wyoming. Buffalo Fork has a watershed which covers 323 square miles.—Wikipedia
Grand Teton National Park is a national park in northwestern Wyoming. At approximately 310,000 acres (480 sq mi), the park includes the major peaks of the 40-mile-long Teton Range as well as most of the northern sections of the valley known as Jackson Hole. Grand Teton National Park is only 10 miles south of Yellowstone National Park, to which it is connected by the National Park Service-managed John D. Rockefeller, Jr. Memorial Parkway. Along with surrounding national forests, these three protected areas constitute the almost 18,000,000-acre Greater Yellowstone Ecosystem, one of the world's largest intact mid-latitude temperate ecosystems.—Wikipedia
