Geomorphological map of the lower NW flank of the Hecates Tholus volcano, Mars (scale 1:100,000)

Abstract

Hecates Tholus (centered at 32.18N 150.28E), is a shield volcano in the Elysium volcanic province, located in the Martian lowlands in the northern hemisphere. Images of this volcano acquired by the Context Camera (CTX) instrument on board NASA's Mars Reconnaissance Orbiter spacecraft show many glacial landforms that have gone unnoticed by previous authors. We present a geomorphological map of the lower northwestern flank of the Hecates Tholus volcano, at 1:100,000 scale, based on the use and analysis of CTX images with a resolution of 6 meters/pixel. The map is organized into a series of geomorphological units (surface cover) and elements (located at a point, along a line or distributed over an area) in order to provide a clearer understanding of the extent of glacial processes and the main dynamic element of this Martian glacial complex. © 2012 Journal of Maps.
