Lower Rainbow Falls, abundant bird life
The Devils Postpile is one of the most impressive examples of columnar basalt in the
world. In layman's terms, this unique geologic formation is created by volcanic lava
flow that cooled, shrunk, and fractured uniformly. The closest rival of any magnitude
is the Giants Causeway in Northern Ireland, and after witnessing the mathematical
precision of Devils Postpile hexagonal columns you'll understand why these natural
displays are given such otherworldly names. This easy day hike also brings you past
upper and lower Rainbow Falls, the former renowned for its 101-foot drop of water
and the frequent rainbows that appear in its misty spray. Additionally, you will exper-
ience a burn-scarred area rich with bird life and regrowth.
DIRECTIONS: Devils Postpile National Monument can be reached from Mammoth
Lakes. From the Mammoth Ranger Station and Visitor Center (on CA 203, 3 miles
west of US 395), head west on Main Street for 1.5 miles and turn right to continue on
CA 203 (Minaret Road), climbing nearly 5 miles to Mammoth Mountain Inn.

ment via car from 7 a.m. to 7:30 p.m. unless you have campground or resort reserva-
