I believe the ice wall thing was a theory proposed by Kent Hovind. Pretty sure he is/was in jail for tax evasion or something? When I was a teenager I ate his young earth creationist stuff up like candy.
Edit: I am aware that the firmament is a thing for a very long time, but I believe Hovind took that idea and proposed it as the reason for his flood and age of the earth theory.
