The Sentry is the slender, curving tower tucked up...
This fin-shaped tower is remarkably similar in structure to the Knight (found lower in the canyon and home to the classic sport route White Knight) except that it is free-standing from the adjacent canyon wall. It is separated from the cliff by narrow corridors on both the uphill and up-canyon sides, and one could potentially chimney about 1/2 up the up-canyon end before the span became too great. The uphill face is a 60' overhanging wave of solid dolomite with many tiny pockets perhaps offering some hard sport routes (haven't been investigated yet), similar to the backside of the Knight. There is also a striking crack splitting the right side of the uphill face. The only route thus far completed on the tower scales the lower 1/2 of the crack and then skirts right onto the uphill arete; the overhanging upper hand to finger portion could be a good hard trad climb. The taller downhill face is rather scabby and not too appealing. The down-canyon arete is overhung and may hold enough features to provide a sport route. The views of the lower trailside walls and of Box Canyon are excellent. All in all, this pinnacle is a cool feature in a remote aspect of the canyon!
The Sentry is found at the far left (up-canyon) end of the third continuous cliff-band rising above the trail. Continue past all of the developed walls on the first band and up the trail until a large triangular boulder with Jack-n-Tina etched into it will be obvious just right of the trail. Go just past this and then bushwhack uphill following the easiest line to the tower above. The Sentry will not be visible until about 1/2 up the hill. It's a bit of a steep slog, but not to much shwacking is encountered. Once at the pinnacle, scramble throught the narrow corridor on the up-canyon end and locate the only striking crack on the uphill face. Approximately 45 minutes from the trailhead.

Follow the lower 1/2 of this crack, which is set in a shallow corner and involves some a series of short cruxy moves separated by rest stances. Small stoppers offer less-than-ideal pro, be careful. Once beneath the bulging upper hand crack, sink in a good #3 camalot and skirt right onto the arete. Follow this for several more cruxy spots to a small ledge. Clip a bolt and crimp up chert past some suspect blocks to the top. An engaging climb that involves much cerebral maneuvering with some ...[more] Browse More Classics in WY
