Colossal Cave Peaks 4282 & 3970
October 25, 2026


Peak 4282 from where I parked


Ascending from the trail to the high ridge


The high ridge and the eastern false summit


Now higher up


A small gauntlet of cliffs to get past


On top the eastern summit, the highpoint comes into view


The summit and cairn


View back northeast at the eastern summit and distant Mica (left) and Rincon Mountains


Pistol Hill looking west


The summit and its eastern subsummit from the trail below


Peak 3970 is next


Partway up the slopes, its big cliff


The top is right there


Summit rocks


Look over at Peak 4282


Montage of views: Peak 3970 as seen from 4282, view of Tucson, some ascent shots while on 3970


Looking down hill of Peak 3970, I'm parked in the clearing to the left
