Water Ice in a Martian Crater

:idea: I noticed in this image (Water Ice in a Martian Crater displayed on 2005 July 20) that there is a hole in the edge of the ice. Also, there appears to be rings radiating out from the hole suggesting that there is a heat source beneath the rim of the ice which melts it in varying degrees over time, creating these rings as the water refreezes. Was this crater created by a volcano or by meteor impact? Could this be a hot spring generated by minor volcanic activity? This might explain how some of the water on Mars reaches the surface. I would love to hear everyone's comments on this because I have yet to find any professional opinion on these anomalies. :roll:
