Signs of Glaciers on Mars?

[Paul Hughen]

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?

 

[Catastrophe]

The climate on Mars about 4 billion years ago is thought to be similar to Earth's now. This period was not so long lived, but it is conceivable that glaciers formed. It doesn't prove anything, but it lends credibility to the model.

"Proof" is not a good word to use in this case. The observed structures do have similarities to glacial moraines on Earth, enticing detailed study of those structures. Considering the structures as glacial moraines is a "working hypothesis," one among some number of multiple working hypotheses.

 

[Catastrophe]

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 ...
