Erosion-resistant Polygonal Ridges Latitude/longitude:-4.80 North, 137.38 East
Rationale: These features are widespread in Gale crater and may be cemented or altered fractures or fracture fill.
Morphology and Mineralogy: Polygonal positive-relief erosion-resistant ridges occurring in the sulfate-bearing, yardang-forming portion of the mound.
What will the rover specifically do here?Determine whether the ridges are erosion-resistant fractures and study their composition to learn more about the post-depositional environment at Gale.
