Today"s image features the Wind River, Arctic National Wildlife Refuge, Alaska, United States. This 136-kilometre long river flows from the Philip Smith Mountains to the East Fork of the Chandalar River, winding through a valley filled with lakes and wetlands. The river begins its journey at Wind River Lake, in the Rocky Mountains near the peak of Togwotee Pass. As it flows through the rugged landscape, it collects water from various forks along the northeastern slopes of the Wind River Range in west-central Wyoming.
