This was shot at Oxbow Bend in Grand Teton National Park. Oxbow Bend is a "bend" of the Snake River which has been cut off from the main channel. It resembles the oxbow used by the western pioneers.

The Snake River is a major river in the greater Pacific Northwest in the United States. It is the largest and longest tributary of the Columbia River, which is the largest North American river that empties into the Pacific Ocean. Rising in western Wyoming, the river flows westwards through the Snake River Plain, and turns north to empty into the Columbia at the Tri-Cities area of the state of Washington, draining 108,000 square miles (280,000 km2) in parts of six U.S. states. The river is 1,040 miles (1,670 km) long, and its average flow is 56,900 cubic feet per second (1,610 m3/s).
Geologically the Snake River watershed ranges from steep mountains to low hills, deep canyons and predominantly, the flat alluvium of the Snake River Plain. The plain originates from a large volcanic hotspot below the North American Plate, which now lies underneath Yellowstone National Park, the headwaters of the Snake River. The catastrophic flooding that occurred during the previous Ice Age, which involved glacial lakes spilling into the middle Snake River, carved out Hells Canyon, the Palouse Hills, and many other topographical features along the middle and lower Snake. Two catastrophic flooding events affected the river. Pluvial Lake Bonneville spilled catastrophically into the Snake River Plain about 14,500 years ago. The Missoula Floods also played a role in the shaping of the lower Snake's watershed, although its effects were more pronounced along the Columbia River.
