The crater is 25km (16miles) in diameter. The floor of the crater is 580m (1,900feet) below the plains surrounding the crater. The crater's rim rises 620m (2,030feet) above the plains and 1200m (3,900feet) above the crater floor. The crater's central peak is 536m (1,759feet) high. The crater's diameter is 40 times the depth resulting in a relatively shallow appearance.[1]
