Looks like an asteroid hit the surface exposing a tunnel???

Looks like Crater Lake in southern Oregon, without water.

They were supposed to close that thing when they were through.

It's a subsidence sinkhole of some kind.I believe there a number of these holes on Mars, and the caverns are essentially lava tubes. Here, it looks like the date of the initial collapse is recorded by the secondary rim, formed by additional accumulation after the collapse, although I couldn't explain the exact mechanism. I think there is a lot of crusty material on Mars formed from compacted windblown dust.

Yes, you can see the door. Just luck that they snapped the picture while it was open.

Yes, a lava tube is a logical cause in this case. The shape simply reminded me of nuclear test sinkholes. The fact that the Mars hole still opens to a cavern is interesting though. It suggests there wasn’t enough surface material in the initial collapse to fill the space beneath it, so if it’s a lava tube it’s a big one!

Thanks for the ping. It is a sinkhole, where the ceiling of a cavern collapsed. But what created the cavern?

Ahhh, it’s probably the kids. I can’t get mine to shut the door after themselves for anything.
