CHIRICAHUA NATIONAL MONUMENT

Chiricahua National Monument is on the north side of the Chiricahua Mountains in the Southeast corner of Arizona. About as far southeast as you can go in Arizona without being in New Mexico or Mexico. This is almost a fairy tale land of Rock spires, pinnacles, balanced rocks, and hoodoos where the laws of gravity don’t seem to apply. Although the park road traverses the park, to fully enjoy this park requires getting out of the car and hiking some of the 17 miles of trails. All the trails in the park are in excellent condition and well signed.


This 12000-acre park was established on April 18, 1924, to preserve the park's natural wonders of weathered volcanic tuff. In 1934 during the great depression, the CCC built the park buildings, many of which still exist today. The many park trails throughout the park today were also constructed by the CCC. Before the monument's 1880s existence, the area was settled by ranchers and, prior to that, the Apaches. The monument has displays on the history, plants, and animals of this unique environment.Geology-wise; when the Pacific Plate was being subducted under the west coast of the North American plate, Arizona was under compression, causing the Mesozoic and Paleozoic rocks to be folded and faulted and older layers were overriding younger. Once the pacific plate spreading ridge reached the North American plate, subduction ceased, and Arizona was now under extension or stretching forces creating an alternating system of mountains and valleys (Horst and Grabens). Early on in the extensional period of Arizona, large pools of molten rock formed under areas of Arizona, and this is where Chiricahua Mountains come in. In an eruption 1000 times greater than the Mount Saint Helen eruption, this magma erupted violently and formed what is known as the Turkey Creek Caldera, a crater 12 miles across. This crater is located in the Chiricahua Mountains in Turkey Creek and west of the Chiricahua ridgeline. The resulting explosion covered the monument with ash over 2000 feet thick, forming the Rhyolitic Tuff that now caps the park. Time and weathering formed the many bazaar rock formations now seen in the park.

If you don’t mind the 2-hour drive from Tucson, Chiricahua Monument is a great place to visit and hike the scenic packed trails. This is relatively remote, so usually not crowded. The four or five times I have been there less than 50 visitors, and at least two of the times less than four cars in the park, and one of them was a park ranger (During the COVID thing).

ED RIGGS TRAIL

Ed Riggs was a CCC supervisor involved in constructing the park trails, and this trail was in honor of him. This is a short 0.6-mile trail that leads from the Massai Point interconnect Trail and heads down to the Hailstone and Mushroom Rock Trails. The Massai Point Interconnect Trail leads to the Echo Canyon Trailhead Parking lot to the north and Massai Point to the south. Access to the Ed Riggs Trail is via the Massai Point Interconnect Trail either from the Echo Park Trailhead or Massai Point at the end of the park road.

The Ed Riggs Trail drops down about 250 feet into Upper Rhyolite Canyon at the junction with Hunt Canyon. There is plenty to see along this trail, although not as impressive as the Echo Canyon Trail. As you drop deeper into the canyon the rock spires rise up on either side of the trail until at the junction with the Mushroom Rock and Hailstone Trails where the views down Rhyolite Canyon are great. From this point, Hunt Canyon to the south and Totem Canyon to the southwest are also visible. Inspiration Point is directly above on the south side of Rhyolite Canyon. This trail is either the starting trail or ending trail of the Chiricahua National Monument great Loop Hike involving almost all the monuments upper trails.
