“The Land of Standing-Up Rocks” is the name that the Apaches gave to the Chiricahua National Monument (NM) area. The name is fitting for the rock pinnacles, columns, and balanced rocks at Chiricahua NM — the remains of extreme geologic activity that continued for millions of years. Eruption of the Turkey Creek Volcano about 27 million years ago, followed by faulting and weathering, gave us the fascinating rock features that led to the creation of the monument in 1924. Various names are given to the rock formations, including pinnacles and hoodoos.
