Hells Canyon is a crater that follows the Snake River in the northwestern United States. The river forms the state border between Oregon-Idaho and Washington-Idaho. The crater is much smaller than the Grand Canyon, however, it is still worth to pay a visit.
Takeoff from Weiser (S87) and follow the river to the north. If you get lost use the GPS map and follow the dotted line (state border). If you set time to morning or evening you will experience the sight of shadows from the mountainsides.
