Things are not always what they seem...

And while I am in geomorphology mode, here's another splendid pic from "Glaciers Online" -- if you look across the ice-covered bay towards the skyline, you'll see a magnificent "pseudo-moraine" near Cape Roberts, Antarctica.  It's actually an ice-pushed ridge on the shoreline -- it must be an incredibly steep shoreline, with very deep water close inshore, because a tabular berg has come trundling in, breaking up the sea ice, and pushing up this considerable ridge of shoreline debris.  If, after the passage of 20,000 years, somebody turns up here and assumes that this is a terminal moraine ridge, which marks the maximum extent of a glacial advance, he or she would very definitely be barking up the wrong tree.
