Hound who had 3 heads; guarded gates of hell.

The arcuate markings in the upper right are in the Amazonis plains and may be sand drifts. The three bright spots, upper left, are volcanoes partially veiled by thin clouds.

A albedo feature is an area which shows a contrast in brightness or darkness (albedo) with adjacent areas. On Mars they are named after names from classical mythology assigned by Schiaparelli and Antoniadi.
