Bereghinia Planitia contains most of the types of terrain found across Venus in radar images. At the center of this image is a radar-dark (hence, smooth) lava flow, whose distribution was controlled by preexisting topography. The flow is itself deformed by numerous wrinkle ridges. Numerous circular features outlined by more wrinkle ridges are some of Venus' many "coronae," whose geologic origin is still enigmatic. The brightest terrain is the highly tectonized "tessera" material.
