A cluster of scoria cones on the SW rift of Halla shield volcano is part of more than 360 flank cones that were erupted during the third and last stage of activity. Most of the cones were built along the SW-NE-trending rift zone that forms the axis of the island. The basaltic scoria cones are typically 150-200 m in height and are relatively uneroded.
