This volcano-like feature is found in Kipling crater and shares similarities to other pyroclastic deposits on Mercury. Where on Earth volcanoes frequently form mountains, on Mercury most of the "volcanoes" that have been identified are characterized by pits or depressions. Described as rimless depressions with irregular shapes, most pyroclastic deposits on Mercury are on the order of a few tens of kilometers in size.
