ally considered a part of Yosemite National Park in 1890. However, aggressive ef-
forts made by mining interests reversed this decision, and in 1905, Congress re-
moved the site from the National Park. Five years later, the Forest Service was ap-
proached by those who wanted to create a rock dam on the San Joaquin River to
power the electricity of their mining operations—a move that would require the dy-
namiting of Devils Postpile. Luckily, the Sierra Club, along with University of Cali-
fornia professor Joseph LeConte, responded with their own lobbying efforts to Pres-
ident Taft, and the area was saved. Christened a National Monument in 1911, the
area once again enjoys federal protection.
At the juncture with the base of Devils Postpile (7,560 feet), turn right to follow
a sign to the top of the columns and begin a short series of switchbacks to see the
basaltic rock formations from above. Like a granite garden of paving stones, it's hard
to believe that the uniformly hexagonal stones were not cut by hand. The columns
were exposed when a glacier traveled down the Middle Fork of the San Joaquin
River some 10,000 to 20,000 years ago, carving away a side of the postpile and ex-
of the stones are scrapes from rocks trapped in the slow-moving glacier. Looking
across the river, there are views of lush Johnston Meadow.
Loop around, descending, and come to another junction. The north trail to the
right leads to the Devils Postpile Ranger Station, Campground, and Shuttle Stop #6.
A free shuttle from here leads back to the trailhead (Shuttle Stop #9) for any weary
walkers. Otherwise, turn left and return toward the rock formations, passing in front
of the basalt columns. The trail begins a short, moderate ascent before reaching a
juncture with a trail toward Red's Meadow or Rainbow Falls. Follow the signs back
to Red's Meadow Resort to return to the starting trailhead.
