I disagree...
..sufficiently strongly with each of those pieces of work to maintain that there is no evidence for glaciations on Mars (other than the fact that there is an ice cap today, of course!)
There are plenty of people who have interpreted the surface features in terms of glaciation but there is, as yet, no hard evidence, IMHO.
But this won't be solved by an episode of "did" - "didn't" so I'll leave the subject for now.
