Kibosch Buttress is in the section of Island in the Sky they call the sand dunes area because of course it is directly across the road from the sand dunes in Snow Canyon. Park at the West Canyon day use parking lot. Walk south on paved road for about 100 yards. Head east across the wash to an obvious scree slope for access to the second tier.
Once on the second tier you need to traverse left until you are below a large roof looking wall.
Kibosch Buttress route follows left into the corner and then straight up and back left out onto the face. It is an easy ramp and varnish slab past seven pins to chains. Although the guidebook calls for medium gear on this route, I felt comfortable not placing any. It also calls for two raps to the ground, (90’), but I used one rope and rapped down to two pins used on the 5.11b Kibosch route. The photos are fairly descriptive.
Many of the routes in Snow Canyon require two ropes for rappels. A dozen quickdraws, small rack of cams and of course helmet and climbing shoes. This is the desert, so plenty of water is never a bad idea.
