This observation targets an approximately 7.5-kilometer rimless crater located within a large bedrock plain. This crater is unusual because nearby craters in roughly the same degradation state still possess raised rims. This crater may thus represent a volcanic vent that is known as a “maar.” A maar is a broad, low-relief volcanic crater caused by an explosion that occurs when groundwater comes into contact with hot lava or magma. The gullies in this crater could also reveal the internal stratigraphy.
