Castle Rock is a 400-foot (120 m) Wingate Sandstone tower standing on a 1,000 foot Moenkopi-Chinle cone above the northeastern border of Castle Valley, Utah. The Tower is world-renowned as a subject for photography and for its classic rock climbing routes, the most famous of which is the Kor-Ingalls Route featured in Fifty Classic Climbs of North America.[3] Castle Rock can be accessed by a trail that begins south of the tower at a primitive camp ground.
Castleton Tower (~40'x400') shares the ridge with a structure at the ridge's Northern terminus with a similar height but considerable larger area known as The Rectory (~200'x1000'). This second structure is also referred to as The Priest and Nuns although those names are more often applied to specific structures connected to or contained in The Rectory. The nearest town is Moab, Utah about 10 miles (16 km) to the southwest and the area is generally accessed from Castleton Road off of Route 128 which runs along the Colorado River between I-70 and Route 191. The La Sal Range and the Manti-La Sal National Forest is visible to the Southeast, The Fisher Towers are visible to the Northeast, and the Colorado River with its associated cliffs lies to the Castleton 's Northwest.
