Ellington Basin and Berkel Crater


Ellington basin, named in 2012 for American jazz legend Duke Ellington (1899-1974), is a peak ring basin covered in secondary craters. The prominent crater Berkel lies inside of the basin. Berkel's ejecta and floor exhibit differences in reflectance and color, indicating a heterogeneous local stratigraphy. This image was created by merging a color image with a monochrome image, in order to emphasize both the topography and the color of the area.
