Measuring Elliot Crater

Explanation: Topographic profile, taken from a preliminary digital terrain model, with crater dimension marked. D = crater rim-to-rim diameter, d=crater depth from rim tip to floor, Dp = width of central peak, Hp = height of central peak. The average crater wall slope, S, is calculated as d/W.
