The Bonneville Slide was a large landslide that took place in the Pacific Northwest of the United States, blocking the Columbia River.
Approximately three hundred years ago a mountain underwent a large landslide, splitting in two and forming Table Mountain and Greenleaf Peak. The southern halves of them slid down the mountain and blocked the Columbia Gorge close to modern-day Cascade Locks, Oregon forming a land bridge approximately 200 feet high. The river eventually removed it, but this event is remembered in local legends of the Native Americans as the Bridge of the Gods.
