Claritas rise is a prominent ancient (Noachian) center of tectonism identified through investigation of
comprehensive paleotectonic information of the western hemisphere of Mars. This center is interpreted to
be the result of magmatic-driven activity, including uplift and associated tectonism, as well as possible
hydrothermal activity. Coupled with its ancient stratigraphy, high density of impact craters, and complex
structure, a possible magnetic signature may indicate that it formed during an ancient period of Mars'
evolution, such as when the dynamo was in operation. As Tharsis lacks magnetic signatures, Claritas rise may
pre-date the development of Tharsis or mark incipient development, since some of the crustal materials
underlying Tharsis and older parts of the magmatic complex, respectively, could have been highly resurfaced,
destroying any remanent magnetism. Here, we detail the significant characteristics of the Claritas rise,
and present a case for why it should be targeted by the Mars Odyssey, Mars Reconnaissance Orbiter, and Mars
Express spacecrafts, as well as be considered as a prime target for future tier-scalable robotic reconnaissance.
