Introduction: Arsia Mons, centered at 8.26°S and (MGS) Mars Orbiter Laser Altimeter (MOLA) topogra- 239.1°E, is the southernmost edifice of the three Tharsis phy [15] that reveal morphologic details and spatial re- Montes volcanoes on Mars. Each volcano has a similar, lationships appropriate for our mapping purposes. overall shape and structure [1, 2], but there are distinct Mapping Methods: Mapping was completed in spatial distributions of morphologic features that hint ESRI’s ArcMap™ 10.2. Line work was drawn at map each volcano has a slightly different evolution history scales of ~1:100,000 to ~1:50,000 with vertex spacing [3]. To determine the differences between these three of 500 m and registered to the THEMIS daytime infra- Martian shield volcanoes, we present a series of individ- red base map. The final ArcMap project includes loca- ual geologic maps of Arsia (this map), Pavonis [4], and tion features (points), linear features (lines), geologic Ascraeus Mons [5] based on high-resolution data sets to contacts (lines), and geologic map (polygons). show their similarities and differences.
