HiPOD: This is Not Hadrian’s Wall
This observation shows us a spectacular long-running ridge located to the north of Vernal Crater. These ridges may be large, mineralized fracture zones. This image was requested to investigate further and take a look at the structure within the ridge, especially with a digital terrain model to help. (Black and white cutout is less than 5 km across; enhanced color is less than 1 km across.)
