There's a great one moving through my head these days--and I would like to net in words that may explain that movement.
Glaciers--glaciated--and the words that are the verbs for the kind of slicing and heaving they do.
Anything you may throw into the big word pit of things glacial I sure would appreciate to help my imagination come to terms with this colossal movement. The after-effects, too, but especially that movement and what happens. Links welcome here...and many, many thanks for whatever you may dig up. (Proper nouns...anything here. Really. Anything.)
Best regards,
WW

When I was a boy I often played on a large hill almost a hundred feet high shaped a bit like half of a football, with points to the north and to the south. It was the only large hill for miles in each direction. I did not know until recently that it was a "drumlin" meaning a place where something managed to resist the bulldozing action of the glacier, forcing the glacier to split and go around it on two sides.

Well, there are always crevasses. Every glacier has some, the more obvious the better, obviously. Nanatuks are the tops of hills which have resisted the ice and are poking up above it. Dunno if that's any relation to Bill's drumlins. But rather than bore you with my definitions of what they are and aren't, here's a link which should tell you everything you would ever want to know: http://www-nsidc.colorado.edu/glaciers/glossary/index.html

Thanks for the link, CK. It reminded me of chuckle I got when a woman added to description of property she wanted to sell that it contained an "esker path". A sly way trying to make a virtue out of fact much of the land was useless because of deep deposits coarse rounded gravel for which there was no demand.
This was material that had collected in a large crevasse, and eventually wound up in an irregular stream at bottom of the glacier fed by melt water. It is believed that the ice was a mile deep until it retreated about sixteen thousand years ago.
Interestingly, pollen studies have indicated that it retreated at about a quarter of a mile per year. No clue as to rate at which it had advanced.

If a glazier installs glass, does a glacier install glace? (Look it up in a French dictionary!)

How do different AWADers pronounce glacier? With a sh sound in the middle (glaysher), or glas (short a)- ier? Or something else?
