As on the Moon, the extent of large impact cratering (i.e. craters too big to have been filled in by erosion since they were formed) serves as an age indicator for the Martian surface.与月球上相同，那些巨大陨石坑的范围（例如，那些巨大到自形成后尚未被尘埃填满的陨石坑）标志着火星表面的年龄。
Also, large blocks thrown aside by the impact would form secondary craters surrounding the main crater.此外，撞击留下的大块物质会在主火山口周围形成二级火山口。
Found as deep as 100 feet from the surface, the springs lie at the base of craters as large as 50 feet wide and 65 feet deep.据发现，距离海水表面100英尺深处，在凹坑基部分布着泉眼，50英尺宽，65英尺深。
