Our objective is to understand nature of the bedrock that has been deformed, here, by the mare-type ridge (a.k.a. wrinkle ridge). In context, it seems possible that the bedrock is sedimentary, but pinning this down is challenging because of the wind-blown dust cover. Where the ridge intersects the impact crater might provide an exposure of subsurface depositional structure and also might show the compressional fault nature of the wrinkle ridge.
