A view of Skunk Canyon looking west from the Mesa Trail showing the Stairway to Heaven route (red line) on Ridge One. The route starts well below the trees from this angle and proceeds up the ridgeline in a series of long steps of alternating 5.4 climbing and 3rd-4th class scrambling. Descent is via the 4th-class gully east of Ridge One (dashed line). The much more impressive Ridge Two (aka Satan's Slab) looms behind.
