The Shirley Mountains are a minor central Wyoming range[tops = 9153] that bounds the southwest side of Shirley Basin. The Shirley Mountains are about 29 miles north west of Medicine Bow, WY. The escarpment/fault faces the Shirley Basin in an "L" shape fashion with the base's east end running west and then turning north. The granite core is the red wall facing east. Among those formations topping the visible granite is a limestone wall above 8000 feet. Along the east west escarpment are some mounds, towers pinnacle and walls with steep faces.

Although only one climb is written up -- posted; there are 18 limestone climbs at the Cliffs Beyond Difficulty  along its west facing cliff.  The easiest climb 5.6 is on the far right and goes to the big caves.   The hardest climb 5.12b is on the left end.  The rest of the climbs range from 0ne 5.8 to mostly 10's and 11's .  Lengths very from 50' to 75' and are well bolted with ram horn top anchors.

Mt Bikers: There are many 2-tract roads on this flat top that make loops and have cool temps and not to difficult for casual mountain biking. Consult the Google map of this region in high detail to see the many 2-track options.

Cavers: There is also a limestone cave out this way. Consult with Rawlins BLM office for key to access.

Safety: Safety trumps Leaving No Trace in this area. You will find hangers on bolts.
