Sentinel Peak is a 2,897-foot peak in the Tucson Mountains, south-west of downtown Tucson. The valley's first inhabitants grew crops at the base of the mountain along the Santa Cruz River, and the name Tucson derives from the O'odham Cuk Ṣon, meaning 'the base [of the mountain] is black'. In the 1910s students of the University of Arizona used local basalt to build a 160-foot block letter A on the peak's east face near the summit, from which it takes its other name, 'A' Mountain. The peak forms part of a 272-acre park, the largest natural resource park in the City of Tucson.
