Lake Michigan is simply an amazing body of water and watching it is much like watching one of the oceans. It’s expanse is only out done by it’s power. We lived over in New Buffalo and watching some of those storms come down the lake was just exhilarating. I’ve seen years when the lake levels were at all time lows (giving us much more beach) and then the lake takes it all back with higher levels and there’s no beach at all. Now I read that Chicago is sinking. Really! This from this mornings Trib. by Tony Briscoe: “The sight lines at Wrigley Field, the panorama from Navy Pier, the vantage points at the Adler Planetarium observatory — all structures built more than 100 years ago are at least 4 inches lower now. In the northern United States and Canada, areas that once were depressed under the tremendous weight of a massive ice sheet are springing back up while others are sinking. The Chicago area and parts of southern Lake Michigan, where glaciers disappeared 10,000 years ago, are sinking about 4 to 8 inches each century. One or 2 millimeters a year might not seem like a lot, but “over a decade that’s a centimeter. Over 50 years, now, you’re talking several inches,” said Daniel Roman, chief geodesist with the National Oceanic and Atmospheric Administration. “It’s a slow process, but it’s a persistent one.” While Chicago’s dipping is gradual, this dynamic could eventually redefine flood plains and work against household sewer pipes that slope downward to the sewer main. The greatest impact of this imperceptible phenomenon likely won’t be inland, however. The contour separating the part of the continent that is rising from that which is falling bisects the Great Lakes. In Lake Michigan, that line passes from Death’s Door at Green Bay in Wisconsin to Grand Traverse Bay in Michigan, signaling that the far northern end is rising while the rest of the lake is lowering. Over time, that has created a tilting effect, generally translating into higher lake levels for the southern end of the lakes and lower watermarks for the northern shorelines. Assuming Lake Michigan’s overall water level stays the same, Chicago’s lakefront will be about 4 inches higher in the next century. The slow-motion, seesaw effect is also happening in other cities on the southern end of the lakes: Cleveland could see a 4-inch swell in Lake Erie’s levels and Milwaukee is projected to see a rise of 5½ more inches. Places such as Canada’s Hudson Bay, which was covered by glaciers up to 9,800 feet thick, are rising up to 3 feet per century.” Global warming, Chicago sinking, the lake levels rising. Anyone one headed to higher ground??
