Laoheishan is one of two scoria cones that formed during the 1719-21 eruption of the Wudalianchi volcanic field and contains a 350-m-wide, 145-m-deep summit crater. A smaller vegetated crater on the NE flank can be seen to the lower left. Laoheishan formed a large portion of an extensive lava field that surrounds it and Huoshaoshan, the other scoria cone that formed during the eruption.
