Hellas Basin Rim Bedrock Plains

Description of the Hellas Basin Rim region

The Hellas Basin Rim region is defined by the northern escarpment of the Hellas Basin proper, situated at a relatively constant elevation of 1000 m above the Martian datum. This forms an approximately triangular region of points south of a line running between the points (32S, 50E), (18S, 62E), and (30S, 82E). The Hellas Basin Rim has 17 mapped bedrock plains.

Geology of the Hellas Basin Rim

This region has been interpreted to be a sedimentary apron built from the transport of materials off the extremely high terrain north of the Hellas Basin into Hellas proper, with later resurfacing by volcanism. (Salese et al. 2016).
