There's an image posted lately on the NASA APOD website you may want to look at. It shows a crater on Mars discovered by the MRO:

http://apod.nasa.gov/apod/ap120718.html

This crater is very odd. No debris around the crater and there's a hole at the bottom of the crater.

Clears,
Joe

Hmm, looks like an Ant Lion hole, where it bores into the sand and forms a cone like hole. I would think it is a sink hole, where the cavern roof collapsed and the sand then ran down into the hole, leaving the cone like structure. Very interesing indeed! 8O

Cool image. The crater looks to me like a frosted over Maksutov.
