Extension

Perhaps the most well-travelled, yet rarely climbed route on Devils Tower, Extension is the crack that is commonly rappelled to descend from El Cracko or Soler. From El Cracko's first-pitch anchors, head right into a shallow but moderate finger crack that peters out into face climbing above. Pass the chains at the hanging belay, surmount the bulge, and carefully pick your way up the small dihedral with a seam. 3 well-spaced bolts protect the moves above the chains, and marginal pro can be found on occasion, but Extension is definitely more runout than most Tower routes. Extension is no classic, but does offer some decent climbing

Start at the anchors at the end of El Cracko Diablo's first pitch.

Nuts, small cams to 1.5" Intermediate bolted anchor, 3 bolts.
