The crater Oskison is located in the far northern hemisphere of Mercury, in the plains north of Caloris basin (PIA10359). Oskison is a distinctive crater with a large central peak that exposes material excavated from depth. In this NAC image, many chains of secondary craters (PIA10178) are visible (green arrows), radiating from Oskison outward onto the surrounding smooth plains. Oskison was just named in November 2008 for John Milton Oskison, a Cherokee author (1874-1947) (see PIA11762).
