Well, for the wiki-thing, I got as far as I could with public sources. Do you know what a pain it is to get images for those articles? Everybody puts conditions on those images, except the USGS, and I squeezed them as far as they could go! All the interesting stuff is behind the pay-wall, and I would never use that as a source, although many poorly-written wikis use them as references, which you can't check up.
So, the knol is "The Great Lakes Controversy"
-starts with a picture of the lakes
-looks like ice lobes, must be ice lobes
-reference to Kiplings 'Just So' stories, how the leopard got its spots, etc
-show pictures related to ice
-the concept of "The Glacial Bulldozer"
My brain has died! I have tons of material, but this looks tedious. I'll need some solid encouragement to keep this going. But for now, I am sinking with the weekend, my blog hits, my ad revenue, and maybe I'll come back Monday... :)
