Small Mounds in Chryse Planitia

The suggested area in this observation is characterized by a group of cones, shield-like features, and round mounds. They are a few hundred meters to kilometers in diameter but their heights are unknown.

Possible explanations for their formation include sedimentary (mud) volcanism and magmatic volcanism. HiRISE data would be essential for distinguishing these hypotheses.
