Did NASA find ancient spaceships on Mars - HRSC follow up

This one might have an easy explanation, or it might not. It’s one of the more unusual GM features I’ve seen and it’s stayed with me since I first saw it on MrVanillaCaramel’s channel. It finally dawned on me to compare HRSC images and see that this is just a crater rendered in some strange way in the GM imagery... but it’s not. Whatever it is, it’s there. Comments sections is now open. Check out MrVC’s vid to hear his description of it and why it seems to be a depression where a craft may have once sat.
