In the far southeastern corner of Arizona are the beautiful Chiricahua Mountains, one of several “sky island” mountain ranges surrounded by expansive desert grasslands. The Chiricahua Mountain Range is an inactive volcanic range twenty miles wide and forty miles long. It forms part of the Mexican Highland section of the Basin and Range Biogeographical Province and rises up dramatically from the valley floor to over nine thousand feet, cresting in a series of uneven, volcanic looking peaks. At the northern end of the range is an extraordinary area of striking geological features and enormous biodiversity. Tucked deep into these steep, forested valleys and beneath the craggy peaks are the remains of violent geological activity that continued for many millions of years—the pinnacles, columns, spires and balanced rocks of Chiricahua National Monument. The Apaches called this place 'The Land of Standing-Up Rocks', a fitting name for an extraordinary rock wonderland. Early pioneers in the late 1800s sensed the unique beauty and singularity of the rock formations in the area. They were instrumental in persuading Congress to protect this ‘Wonderland of Rocks’, so much so that in 1924 the Chiricahua National Monument was created.

There are approximately twelve thousand acres of wild, rugged terrain within which the rock formations and a great ecological diversity are protected. In 1976, Congress decided to further preserve the land, designating 87% of the monument as Wilderness. This precludes any development and human intervention, thus ensuring the preservation of the geological formations for future generations and the continuation of undisturbed space and habitat for the many unique plants and animals that are found in this special region. As well as the exceptional geological aspects of this park, the monument hosts a biological crossroads, a meeting-place of four different ecological regions. In the Chiricahua Mountains, the Sonoran and Chihuahuan deserts, and the Rocky Mountain and Sierra Madre ranges all meet. The convergence of these four biomes makes this area unusually rich in both floral and faunal biodiversity. Rocky Mountain representatives such as the Ponderosa pine and Engelmann spruce co-exist beside the Soap tree yucca from the Chihuahuan desert. Stately Arizona sycamore and various types of oak dot the well-watered canyons. Apache pine grows here at the most northern end of the Sierra Madre range. Chihuahua pine is found, as are Douglas and White fir, Arizona cypress, Cane cholla, Prickly pear and several species of ferns, mushrooms, and fungi. There are five major drainages within the monument, several with intermittent creeks that support a mixture of deciduous and evergreen woodlands. The heavily forested canyons provide habitat for numerous wildlife, including coatimundi, white-tailed deer, javalina, and many species of birds; over three hundred bird species are found in the Chiricahua Mountains, some of whom have migrated north from Mexico.

The Chiricahua Mountains are part of the Madrean Archipelago, a collection of forty neighboring mountain groups that lie between the Colorado Plateau and the Sierra Madre Occidental. It is so named because it resembles an oceanic archipelago - a sea dotted with islands - only here the sea is hot desert grassland. We call these isolated mountain ranges ‘sky islands’. The Chiricahuas are a perfect example of a sky island that formed during the Basin and Range faulting.

Four biomes meet in Chiricahua National Monument

The Chiricahua Mountains are a crossroads for plants and animals from four ecosystems; the Rocky Mountains to the north, Mexico’s Sierra Madre Mountains to the south, the Sonoran and Chihuahuan Deserts.
