Gibbon Falls drops 84 feet (0.3 m) over a remnant of the Yellowstone caldera rim. The caldera was created by a massive volcanic eruption approximately 640,000 years ago.
Subsequent lava flows filled in much of the caldera, and it is now measured at 30 x 45 miles. Its rim can best be seen from the Washburn Hot Springs overlook, south of Dunraven Pass. Lewis Falls, Lake Butte, and Flat Mountain Arm of Yellowstone Lake are also part of the Yellowstone caldera rim.
Arctic grayling, an entirely stream-dwelling fish, was historically common in the Gibbon River below Gibbon Falls. They are now occasionally present in the Gibbon River.
Think Safety, Act Safely
From burning hot hydrothermal features, to unpredictable wildlife, to steep terrain, Yellowstone is a dangerous place. You are responsible for your safety. As such, please remember these safety tips:
- Never touch any hydrothermal waters—they can scald you.
- Observe safe distances from all wildlife.
- Stay behind fencing, guard rails, and ledges.
- Use caution when around park waters—they are cold and fast.
- Show patience and courtesy to other people.
