The Bear River is the largest tributary of the Great Salt Lake, draining a mountainous area and farming valleys northeast of the lake and southeast of the Snake River Plain. It flows through northeastern Utah, southwestern Wyoming, southeastern Idaho, and back into northern Utah, in the United States. Approximately 350 miles (560 km) long it is the longest river in North America that does not ultimately reach the sea.

The Wasatch Range or Wasatch Mountains is a mountain range in the western United States that runs about 160 miles (260 km) from the Utah-Idaho border south to central Utah. It is the western edge of the greater Rocky Mountains, and the eastern edge of the Great Basin region. The northern extension of the Wasatch Range, the Bear River Mountains, extends just into Idaho, constituting all of the Wasatch Range in that state.
