This fresh-appearing, unnamed crater is located in the northern plains of Mars, west of the Elysium Mons volcano.
The crater is approximately 6 kilometers in diameter with a prominent raised rim and lobe-shaped ejecta blanket. The distal margin of the ejecta forms a distinct outer scarp (cliff or rampart) suggesting that the crater formed in terrain where the subsurface was ice-rich.
Gullies have formed on the inner slopes of this impact crater. However, the gullies on the crater’s northern, pole-facing slope have eroded more deeply into the surface suggesting that water and ice may have also played an important role in gully formation.
