The low albedo (dark) patterns may indicate pyroclastic (explosive) material that erupted over 3 billion years ago. Tobias Mayer G crater (7000 m diameter) is seen in the upper left in this west-to-east view. Width of the image is about 30 km. Incidence angle 44°, slew angle 68°, phase angle 36°, NAC M1252131209LR [NASA/GSFC/Arizona State University].
