In this observation, we have contact between a ridged unit and a presumed underlying non-ridged unit. Our goal is to see if the ridges penetrate both units or are confined to just the upper unit. Vernal is about 56 kilometers in diameter, and contains formations that resemble springs like we find on Earth.
