Description
Once part of California's Yosemite Park, the Devils Postpile returned to protection of the National Park System as a National Monument in 1911. Located in a valley under some of the most rugged peaks of the Sierra Nevada Moutain Range, the park often receives more than 400 inches of snow each year, closing the park during winter months.
Although some details of the geologic history of the Devils Postpile are not completely clear, geologists have pieced together much of the past activity near this continental subduction zone. The park's main feature, the columnar basalt columns, were formed from a plug of cooling lava nearly 100,000 years ago.
