went at it with one another. (Pow!) ;-)

But, I don't see anything in your paper that supports your claim, viz:

"I would like to think that my eyes are open, and I can tell a Maar from a tuff ring from a crater. Like this..."

(Since the topic is phreatic cones aligned along flow ridges, and whether CO2 or H2O (or both) is the operative volatile, etc. Nothing about maars, tuff rings and other processes that can produce circular formations without impact. Here's a clue: You say, "Clearly, flows cannot be both hot and cold at the same time..." Why not? Is your statement true? Are there circumstances in which a flow could be simultaneously hot and cold? Could those circumstances obtain on Mars?)
