Chiricahua Peak, Mountain summit in Chiricahua Mountains, Arizona, United States.

Chiricahua Peak is a 9,773-foot (2,979 m) summit in the Chiricahua Mountains of southeastern Arizona, about 35 miles north of the Mexico border and the highest point in Cochise County. Its upper slopes hold one of the world's southernmost Engelmann spruce stands, with quaking aspen thickets on the north slope. Much of the peak burned in the 2011 Horseshoe 2 Fire, and aspens now occupy ground once held by evergreens.

Chiricahua Peak is the remnant of a volcano that erupted about 27 million years ago, building the Chiricahua Mountains of southeastern Arizona. Geological surveys of the mountain have identified more than 210 kinds of rock; rhyolite, dacite and porphyry form its base. In 2011 the Horseshoe 2 Fire burned 223,000 acres (90,000 ha) across the range, damaging much of the trail system, and most paths still receive only infrequent volunteer maintenance.

The Chiricahua Mountains lie in the traditional homeland of the Chiricahua Apache, the band led in the 19th century by Cochise and later by Geronimo. The range's name comes from that people. Visitors today walk the same canyons and ridges where these groups moved between the mountains and the desert below.

The peak is reachable via Mormon Ridge Trail or Mormon Canyon Trail, though winter weather can require special gear for the final push to the summit. Visitors should prepare for possible snow and ice on the upper sections of the route.

The Engelmann spruce here mark one of the southernmost stands of the species in the world, not just North America. The 2011 Horseshoe 2 Fire burned much of the summit, and quaking aspen has since taken over ground once held by evergreens. Look for aspen groves on the north slope.
