Aricia Tholus, Vesta
Aricia Tholus is a hill on Vesta with a relatively fresh impact crater at its peak. The ejecta from the impact crater is some of the darkest material on the surface of Vesta. This photo combines color images taken during Dawn's High-Altitude Mapping Orbit with higher-resolution images taken during the Low-Altitude Mapping Orbit. The HAMO images were obtained by Dawn on October 26, 2011 and the LAMO images on April 30, 2012.
Here is the HAMO image:
