The Devils Postpile National Monument is located in the Reds Meadow Valley in the Sierra Nevada in the US state of California. The basalt cliff goes back to a lava flow that emerged from a volcanic eruption around 100,000 years ago about 3 km above today's area. It flowed into a basin that was originally not quite 150 m deep and slowly cooled down in it. The slow and even solidification of the lava to basalt is the reason why the hexagonal columns in the area are among the most regular occurrences on earth. In the last ice age about 10,000 years ago, the valley was carved out by a glacier and the pillars exposed from the side and top. Due to the erosion, around 20 m from the bottom of the original formation are still preserved today.

One of my favorite places! I try to get there every year to fish for trout in the San Joaquin River which runs right past the Postpile. It is nestled on the backside (west side) of Mammoth Mountain and is only accessible via a tiny one-lane mountain road for 6-7 months of the year due to snow, and the Pacific Crest Trail goes through the valley. Hike from the Postpile south to Rainbow Falls for incredible scenery, not to mention more good trout fishing. Brookies, Rainbows and Browns are everywhere, but one can occasionally catch a Golden trout in this location. Catch all 4 species in a day to achieve the "Sierra Slam."   |
