50-mile diameter crater has mile thick ice was created by RocketDawg

Here's an interesting article about a large crater that's filled with ice that was discovered by ESA's Mars Express.

Yes, that is pretty interesting, and located not too far from the north pole of mars at 73N. The article didn't say, but presumably both are water ice and not carbon dioxide.

This one is excellent. I have to find this one and check it out. Have never seen it. The sides of the crater are amazing as well. All sorts of geometry.

I checked out the HiRISE photograph and it seems these strange features in the bottom of the crater look like sand dunes, rather strange geology for an area close to the North Pole.

Thank you to everyone who has stuck by the YouTube channel and to all of our admins and forum users here on the channel. They really have kept the website current while I have been busy taking care of things in my personal life. I promised that the next video would be a long one and have a LOT to look at. You can get lost in these Gigapans and I really hope that you do! I spent a lot of time stitching these together and making sure that they were the best quality that I could get them. SOL 1448 really has been a goldmine for anomaly hunters and those people who are just hobbiest. I really hope you enjoy this one and expect much more to come from the latest batches of images!
