From the front side of Castle Rock a small arch is visible to the left. Below the arch are the rubble remains of some of the estimated 40 to 60 rooms that served 75 to 100 residents. In the notch at the top right, there appears to be a log floor with two courses of stone bricks.
Hiking past Castle Rock on the west side there the spur trail leads around the back side to a large section of preserved wall. This seems to be a particularly thick wall section.
The habitat here is Pinon Pine and Utah Juniper forest. There is water in McElmo Creek slightly to the south but there doesn't appear to be permanent water in the vicinity of Castle Rock.
