Its columns of lava, with their four to seven sides, display a honeycomb pattern of order and harmony. Another jewel in the Monument is the San Joaquin River. Along the river corridor, the Monument flourishes with life.
Meadows burst forth with flowers that nourish deer, birds, and butterflies.
This portion of the San Joaquin is a designated Wild Trout River where both novice and expert can play the waters for four species of trout. In addition to its geologic wonders and the beauty and diversity of the San Joaquin River, the monument is a portal to the great Sierra backcountry. At 800 acres, Devils Postpile National Monument may be considered small by some, yet its natural and recreational values abound.
