Rampart crater
From Wikipedia, the free encyclopedia
Rampart craters are a specific type of Martian impact crater which are accompanied by distinctive fluidized ejecta features. The craters are considered to be evidence of ice or liquid water beneath the surface of Mars. The impact melts or boils the water in the subsurface producing a distinctive pattern of material surrounding the crater.
