Bassett Peak

High point of the Galiuro Mountains sky island in Coronado National Forest, Graham County—mid-Tertiary block-faulted volcanic and sedimentary range between the San Pedro and Sulphur Springs valleys. Summit ridge and approaches expose the Galiuros’ stacked volcanic stratigraphy and fault-bounded relief; long wilderness approaches (Powers Garden / Rattlesnake Canyon country) make this a serious backcountry geology and peak-bagging destination, not a roadside pullout.
