The interior of the Cerro Chopo pyroclastic cone has been exposed by extensive quarrying operations to provide aggregate materials for road construction. Reverse grading can be observed in walls produced by the quarrying. The cone rises about 250 m above its base to 402 m elevation. The crater is oriented to the NW and was the source of olivine-basaltic lava flows.
