If Asian carp ever get into the Great Lakes, fun in boats as shown above could well be a thing of the past. These invasive fish jump out of the water when disturbed by noise and vibrations. With an average weight of 30-40 pounds and some weighing in over 100 pounds, they can cause injury or death to boaters.
The Freep reports that a plan tentatively recommended by the Army Corps of Engineers to keep Asian carp from the Great Lakes would cost $275 million plus annual costs for maintaining and operating it of nearly $20 million a year:
Of all the options considered by the Army Corps for blocking the advance of Asian carp at the Brandon Road Lock and Dam in Joliet, Ill., the tentatively selected plan was the most expensive. It would use noise to block the fish, along with an electric dispersal barrier, water jets, a flushing navigation lock and more.
…The plan, however, doesn’t guarantee success: The Army Corps estimated the species known as Asian carp would still have a 10%-17% probability of becoming established in the Great Lakes, down from 22%-36% if no action was taken.
The Corps estimated that closing the navigation lock altogether would have the greatest likelihood of stopping bighead carp and silver carp — the two invasive species that are known as Asian carp — from reaching Lake Michigan, bringing the probability down to 1%-3%. But the cost to inland shippers and the companies they serve would be in the hundreds of millions of dollars with some shippers going out of business.
I hate to be a jerk, but PUT THOSE SHIPPERS OUT OF BUSINESS. Asian carp in the Great Lakes would be a disaster* and seriously impact BILLIONS OF DOLLARS in wages tied to the health and recreational value of the Great Lakes.

Lake Michigan … barge pushing, photo by Ken Scott Photography
Here’s a shot of a familiar vessel, the St. Marys Challenger. As this article on the conversion of the Challenger says, eventually, age catches up with you:
St. Marys Challenger lived up to its name by defying that assertion longer than its counterparts. But after 107 years, the laker was taken out of service in November 2013 to be converted to a barge. Built in 1906, Challenger was the oldest operating freighter on the Great Lakes.
The decision to convert the 551-foot cement carrier followed a series of upgrades spanning several decades, including extensive hull rebuilding, installation of a self-unloading cargo system and a myriad of other structural upgrades. In the end, the owner was left with a Skinner Marine Uniflow four-cylinder reciprocating steam engine burning heavy fuel oil, outdated DC electric and an aged mechanical propulsion system that made operating the boat an ever-increasing expense.
…Port City Marine, based in Muskegon, Mich., considered its alternatives, including retrofitting Challenger with a diesel engine. Not only would that have cost about $20 million — nearly double the barge conversion project — but it would have saddled the company with ongoing expenses. And while a crew of 25 was needed to operate Challenger, the articulated tug-barge (ATB) can operate with 11.

Manitou Islands in the morning, photo by Glen Arbor Artisans
North and South Manitou Island are part of an island chain that extends north to the Straits of Mackinac and includes the Fox Islands and Beaver Island. South Manitou Island is just over 8 square miles in land area and is about 7 miles from Glen Arbor while North Manitou Island is about 22 square miles and a little over 10 miles from Glen Arbor. More about the Manitou Islands from the Sleeping Bear Dunes National Lakeshore.

Sunset Waterspout, photo by Kyler Phillips
The National Weather Service in Gaylord has a page on the Science of Waterspouts that says in part:
Dr. Joseph Golden, a distinguished waterspout authority with the National Oceanic and Atmospheric Administration (NOAA), defines the waterspout as a “funnel which contains an intense vortex, sometimes destructive, of small horizontal extent and which occurs over a body of water.” The belief that a waterspout is nothing more than a tornado over water is only partially true. The fact is, depending on how they form, waterspouts come in two types: tornadic and fair weather.
Tornadic waterspouts generally begin as true tornadoes over land in association with a thunderstorm, and then move out over the water. They can be large and are capable of considerable destruction. Fair weather waterspouts, on the other hand, form only over open water. They develop at the surface of the water and climb skyward in association with warm water temperatures and high humidity in the lowest several thousand feet of the atmosphere. They are usually small, relatively brief, and less dangerous. The fair weather variety of waterspout is much more common than the tornadic.
Waterspouts occur most frequently in northern Michigan during the months of August, September, and October, when the waters of the Great Lakes are near their warmest levels of the year. Waterspout formation typically occurs when cold air moves across the Great Lakes and results in large temperature differences between the warm water and the overriding cold air. They tend to last from about two to twenty minutes, and move along at speeds of 10 to 15 knots.

Empire Bluff, photo by Pantheos
The author of my favorite Michigan blogs writes that Michigan is blessed with some of the most beautiful and tallest coastal sand dunes on the planet. He decided to climb some and put together a big old list of 87 Michigan’s ‘skyscraper’ Coastal Dunes that he could verify at 100′ or more in height.
This photo is from the tallest one, the 526-foot Empire Bluff Dune in the Sleeping Bear Dunes National Lakeshore (which includes many of the tallest). To put this in perspective, it’s almost exactly 200′ shorter that our tallest building, the Renaissance Center in Detroit as well as One Detroit Center and the Penobscot, but it’s taller than the 4th highest – the Guardian Building.
