Hiking back to the car, the first 2 routes are jus...
Decent limestone crag that features mostly shorter routes on vertical rock. Gets excellent winter sun (noon until sunset).
Park at the Bair Ranch rest stop (exit 129) just east of Glenwood Springs. Cross under the highway to the north side and locate an obvious concrete water culvert. Walk around a barbed wire fence via the left edge of the culvert, then head up along the left side of the drainage and over a second barbed wire fence. From here follow a good climbers' trail up to the right end of the cliffs, and traverse west (left) along a catwalk-like ledge system all the way to the SW end of the cliffs. Just before rounding the corner is a cave with two steep routes, and once around the corner most of the routes are found.
The Surgery Buttress is one of my favorite crags in Glenwood Canyon. Easy access and great rock with fun routes. Afternoon sun or morning shade, depending on what you're looking for. Dries out quick.
