Characteristics of Alba Mons lava tubes: western flank study area

<strong>Description</strong> The data archived here include specific results from geologic mapping studies of the Martian volcano Alba Mons associated with the publication 'Distribution and Morphology of Lava Tube Systems on the Western Flank of Alba Mons, Mars,' submitted to the JGR/ESS Special Issue on Planetary Caves: Exploring Planetary Caves as Windows into Subsurface Geology, Habitability, and Astrobiology. <br> These results were generated from analyses of imaging and topographic datasets acquired from spacecraft orbiting Mars, and were used to provide descriptions and quantitative characteristics of lava tube systems on the western flank of Alba Mons. Included here are two tables containing data associated with Figure 10 (map of lava tube segments) and Figure 11 and Tables 1 and 2 (associated morphologic and morphometric parameters) of the publication. More details of the study can be found in the publication. <br> <strong>Citation<br> </strong>When using these data, please cite the following with the appropriate version number: <br> <em>Crown, D.A., Scheidt, S.P., and Berman, D.C.
