Unusual mountain formation on Mars

On the images taken from the orbit an unusual mountain formation is depicted, which seems to have resulted from weathering (erosion) and is located amid the frozen ocean. The given formation drop-like shape (in section), its evidently erosion origin and the unusual structure at the base, which might be conventionally called a 'door' for its physical resemblance, are of interest.

The object unusual form and the presence of a 'door' do not mean the mountain formation is of artificial origin. The mentioned peculiarities are of primary interest because of their morphology.
