A three-sided pyramidal formation located within the Candor Chasma region of Mars is examined. The formation is presented in five NASA images provided by the Mars Global Surveyor (MGS) and Mars Reconnaissance Orbiter (MRO) spacecraft. The images reveal defining aspects of the formations three-sided Reuleaux geometry, exposing a uniform symmetry in its three, triangular faces. A geologist and a geoscientist examine natural mechanisms that could contribute to the creation of the pyramidal formation and a claim of intelligent construction is proposed. An extensive search of comparable regions within and beyond the area of Candor Chasma was conducted and terrestrial comparisons are also offered. A request for additional images is recommended and a broader study of this anomalous formation is encouraged.
