15,000 to 10,000 years ago, during the last ice age a huge lake covering 3,000 square miles of western Montana and held back by glacial ice, formed and emptied about every fifty years. Each time the ice dam broke the lake emptied in days and huge waves of water, rushing hundreds of miles to the ocean, created many unusual geologic features like the Columbia River Gorge, the rolling Palouse hills, the flat, fertile Willamette Valley and the 400’ high cliffs of Dry Falls.
The parking lot of the center features a walkway with good views of the dry falls along with interpretive signs. There are also inside exhibits and a store that we didn’t visit.
The walkway, including a portion that juts out onto a pinnacle of rock, is accessible. Viewing of the dry falls and the signs is easy from a seated position. The inside exhibits are accessed by a stair lift that must be unlocked and operated by a ranger. We skipped it because so much information is provided outside.
The parking lot is large enough for RVs. Falls
