Here's a pic, Curious George will love. I picked this up on my way into a government hydrologist, USGS, Corp of Wngineers town hall meeting when everybody was in a panic about Great Lake Levels.
After listening to harrowing stories about what could happen and whom to write letters of concern, I raised my hands for the Q&A.
A aksed what Lake Michigan looked like 10,000 years ago and the pencil neck said three words: Miniature Grand Canyon. Then I asked where is the rest of the data because this chart I have here doesn't even go back 100 years. Needledick said that's all the data.
