The Amenthes Quadrangle: A Map of Mars

Named after the mythological Egyptian underworld, the quadrangle was formally mapped by the USGS Astrogeology Research Program to standardize the nomenclature and topographical data of the Martian surface.

Key features include the Amenthes Rupes, a prominent scarp, and various lobate debris aprons, which provide evidence of past glacial or periglacial processes.

The Amenthes quadrangle is a defined mapping region on Mars, spanning 0°–30° N and 225°–270° W. It serves as a primary study area for understanding the dichotomy between the southern cratered highlands and northern plains.

The region is significant for its diverse geomorphology, including evidence of fluvial activity and mass wasting, which are essential for reconstructing the climatic history of Mars.

Data acquisition relies on remote sensing instruments, including the Context Camera (CTX) and High Resolution Imaging Science Experiment (HiRISE), to map surface morphology and mineralogical composition.
