Light-toned mounds on the floor of Kashira Crater exhibit signature of aluminum-phyllosilicates or hydroxylated silica in CRISM multispectral data. Mars Orbiter Camera images show networks of ridges on the mound surfaces, possibly resistant fractures resulting from alteration or cementation by fluids. Some surfaces have a polygonal texture.
