Introduction: Moulton crater (~50 km in diameter, Information from the WAC, NAC, LOLA, and D, 61.1° S, 97.2° E) is located in the Southern Clementine data in this region was then used to delimit Hemisphere, on the lunar farside. Its location makes this geologic contacts within the map area. The units derived crater impossible to study from Earth-based from this process were given brief descriptions, relying observations. However, since 2009, the Lunar primarily on morphologies and interpretations of Reconnaissance Orbiter Camera (LROC) has been composition. systematically imaging the Moon with its Wide Angle Results and Discussion: A basic geologic map with Camera (WAC) and Narrow Angle Camera (NAC) [1], compositional and morphologic interpretations was providing the means to photo-geologically map this created by refining boundaries visible in WAC imagery region. using NAC imagery and attempting to identify more With NASA’s return to lunar exploration and a focus detailed geologic features (Fig 1). Clementine UVVIS on the South Pole, Moulton crater is worth studying in data also provided compositional information to help greater detail to understand how it fits into the broader identify contacts between different units in this geologic context of the region, as it contains a record of the map. Though it was difficult to derive a complete intersection of several geologic processes.
