Conical Crater, Fig. 1

Lunar mare crater Euclides (left) and topographic profile derived from Lunar Reconnaissance Orbiter stereo images (Scholten et al. 2012) (right). The walls are conically shaped with a slope of about 33°, and the floor area is flat and small as compared to the rim area (about 5 %). This marks the basic structure of a conical crater (LROC M196693772CE image: NASA/GSFC/Arizona State University)
