Arnold (crater)
The ancient rim of Arnold has been worn and rounded by ages of subsequent bombardment. There is a gap in the wall to the southwest, marked by the tiny crater Arnold J, and the wall is relatively low along the eastern edge. The northern half of the rim is the most intact, particularly to the northeast where is joins the satellite crater Arnold A.
The inner floor of Arnold crater has been resurfaced by lava, and is relatively flat except for a number of tiny craterlets. The most notable crater in the interior is Arnold F, in the northwest section. If the crater once possessed a central peak, no sign of this feature now remains.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Arnold.
