The raised ridges that Ingenuity flew over in its tenth flight look a lot like glacial moraines. Could this be proof of not only liquid water but glacial movement?

On Mars, scientists have identified probable moraines that were left by glaciers that formed on the northwest sides of the four giant Tharsis volcanoes. But these moraines lie on top of delicate landscape features that a moving sheet of ice would totally destroy.

Some appear to have a hollowed out center, looking like a glacier after almost all the ice has disappeared. What is left are the moraines—the dirt and debris ...
