Devils Postpile NM is an incredible example of columnar jointing. This geologic formation was created when one hundred thousand years ago, lava flowed through the valley and settled like a pool. As the lava cooled, it shrank and the basalt cracked in 120 degree angles. Several thousand years later, a glacier flowed along the top uncovering the formation and smoothing the tops of the columns. A majority of which are six sided. Dylan became a jr ranger at the monument
