Ap corral 3 is located 0.47km south of Korbulag village, just 100m south of Stela A1 (map quad C5a).
The corral was built atop a low hill in an area where small rises alternate with shallow lateral basins.
This corral measures 24m in diameter and was built using both unworked basalt blocks and an outcrop of bedrock. The bedrock was utilized as one segment of the corral's arc while boulders were used to create the rest of the circle.
No surface materials.
