1981 Map of Mt. Lemmon

USGS Topo · Published 1981

About this map

Summerhaven and the surrounding high peaks of the Santa Catalina Mountains are captured in this 1981 survey, reflecting a landscape defined by seasonal retreat and scientific installation. At the summit of Mt Lemmon, the map identifies an Observatory, Radio Towers, and a Heliport, highlighting the peak's importance for observation and communication. The settlement at Loma Linda and the nearby Catalina Camp show the concentrated development along the Mt Lemmon Highway, while the remainder of the terrain is dedicated to the Coronado National Forest and the Pusch Ridge Wilderness. Information-gain for researchers is found in the specific naming of dozens of remote water sources like Wooden Trough Spring and Flicker Spring, alongside legacy mining sites such as the Hartman Homestake Mines on the eastern slopes of Oracle Ridge.
