Devils Postpile National Monument, Mammoth Lakes

4.6
#1 of 13 in Nature in Mammoth Lakes
See rare geometrically shaped basalt formations and 30 m (100 ft) tall waterfalls at Devils Postpile National Monument, which is within the Ansel Adams Wilderness. The formations were created 100,000 years ago when lava was flowing and cooling down and glaciers eroded, polished, and fragmented the basalt into long, symmetrical columns. Reaching 18 m (60 ft) high and ranging from 61 cm (2 ft) to 1.1 m (3.5 ft) in diameter, the formations give an impression of tall posts stacked in a pile. At the park, you can hike, camp, fish and go horseback riding. Look for animals, such as black bears, coyotes, and mule deer. You can explore on 13 km (8 mi) of trails on your own or on a guided tour.

  • Oh my God. We had a great walk in the park. I love this stones. It's amazing. There is a fall near it too.
  • This is amazing place. You can see strange rock pillar and splendid waterfall. We met the big hail during the hike, but the view is really amazing. You can see yellow trees with snow ball on the ground. So pretty!
