Above the saguaros and open desert foothills, the summit opens into broad views over Tucson and the surrounding ranges. Look east toward the Rincon Mountains and north toward the Santa Catalinas; on a very clear day, Picacho Peak may show to the northwest. Take a moment to turn all the way around instead of treating the summit as a quick photo turnaround.
For a photo, use a saguaro or rocky ridge in the foreground, with Tucson and the farther ranges beyond it. That gives a better sense of distance than pointing at an empty skyline.
