file Strange Triangular Depression in Hellas Planitia

From HiRISE image PSP_008347_1360 of Hellas Planitia there appears this unusual triangular depression. It looks less like a landslide and more like an excavation site.

I'm convinced. I am having difficulty with the scale though. About how long is one of the sides of this triangle?

Each side is approximately 900 pixels in diameter. With an MP scale of 50cm per pixel, I come up with 45,000cm or 0.45km.

It looks like we have some kind of settlement along the top. Rows of houses, streets?

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!
