De Graft Crater and Rays from Hokusai


A colorful view of a complex region is shown in this image. The high-reflectance and hollow-filled floor of de Graft crater is visible at center left, and a similar high-reflectance smaller crater is located to the northeast. Streaking across the scene from north to south are rays from Hokusai crater, located over 1,500 km away.
