0414-EVA8Report

Crew members: Commander Karen Rucker, Executive Officer Drew Canham, and Engineer Jaxom Hartman

Locations:

12 N 518524 4249129 (sedimentary rock field)

12 N 519235 4251489 (ancient Fluvial Area)

ATV: 1, 2, 3

Time: 13:45 departure – 16:00 pm return

Purpose: Geology EVA. Teach students about sedimentary rocks, deposition, lithification, and examination of the regolith. Perform Monsell Soil Color analysis, use Brunton Compass to determine strike and dip. Collect soil samples for analysis using sieving at the lab.

Summary:

Departure for this EVA was slightly delayed due to morning EVA and lunch. The locations for this EVA were chosen in order to study different kinds of geologic structures and the methods by which they were created. The pattern of lithification in the sedimentary rock field was very unique and interesting to the crew, and a Brunton compass was used to determine “strike and dip” of a hoodoo. Former evidence of a vigorous fluvial environment was observed at the second location.
