Pinaleno Mountains - Heliograph Station

Heliograph Station

Heliograph Peak was home to a 19th century heliograph station. "During General Nelson Miles' mid-1880s campaign against the Apaches led by Geronimo, a U.S. Signal Corps officer named Colonel William A. Glassford established an innovative signal system. Atop mountain peaks throughout southeastern Arizona and southwestern New Mexico, soldiers manned stations using mirrors, or heliographs, to flash messages across great distances. Heliograph Peak, as one of the highest mountains in southeast Arizona, served as one of the peaks in that system. Miles cornered Geronimo in 1886 and had him sent into exile in Florida. As a reward for their efforts, the Apache scouts that had helped defeat Geronimo were sent into exile along with him. Shortly thereafter, the heliograph system was abandoned along with a number of forts used in the Apache campaign."
