A large crevice,stretching almost two football fields,suddenly appeared in the wood near Birch Creek.
MENOMINEE TOWNSHIP-It's a geological phenomenon that has both authorities and Menominee Township residents scratching their heads.

Unexplained Crack Splits UP Backyard

BIRCH CREEK, Mich. - A Michigan family's property has a sudden unexplained divide.
A large unexplained crack now runs 200 yards through the Salewsky family's property, eight miles north of Menominee in Birch Creek.
The family thinks it happened yesterday around 9:00 in the morning. The ground raised five feet up, taking trees along for the ride.
Some cracks were up two feet wide and five feet deep.
"The house shook, the chairs shook," Doug Salewsky said. "The logs weren't there when I piled them."
Salewsky doesn't know what caused his backyard to split in two and neither do police.
There have been no recent reports of any earthquakes in the area.
People specializing in geological surveying are being called in to try and explain the phenomenon.

On Monday morning, 04 October 2010, a large noise and shaking were observed in a small area north of the town of Menominee, in Michigan’s Upper Peninsula. The following day, a local resident returned to the site of a fallen tree that was being removed for firewood, and observed a large crack in the ground. This feature was reported to local officials, who contacted Michigan Tech, and the news media.
On Sunday, 09 October, Dr Wayne Pennington, Chair of the Department of Geological and Mining Engineering and Sciences of Michigan Technological University, visited the site (figure 1 and figure 2). The following is a report of observations and tentative conclusions...

An escarpment is a steep slope or long cliff that occurs from erosion or faulting and separates two relatively level areas of differing elevations.
Most commonly, an escarpment is a transition from one series of sedimentary rocks to another series of a different age and composition. When sedimentary beds are tilted and exposed to the surface, erosion and weathering may occur differentially based on the composition. Less resistant rocks will erode faster, retreating until the point they are overlain by more resistant rock (see cross section schematic). When the dip of the bedding is gentle, a cuesta is formed. Steeper dips (greater than 30-40°)[2] form hogbacks.
Escarpments are also frequently formed by faults. When a fault displaces the ground surface so that one side is higher than the other, a fault scarp is created. This can occur in dip-slip faults, or when a strike-slip fault brings a piece of high ground adjacent to an area of lower ground.

The Niagara Escarpment is a long escarpment, or cuesta, in the United States and Canada that runs westward from New York State, through Ontario, Michigan, Wisconsin and Illinois. It is composed of the Lockport geological formation of Silurian age, and is similar to the Onondaga geological formation, which runs parallel to it and just to the south, through western New York and southern Ontario. The escarpment is most famous as the cliff over which the Niagara River plunges at Niagara Falls, for which it is named.
The Niagara Escarpment is the most prominent of several escarpments formed in the bedrock of the Great Lakes basin. From its easternmost point near Watertown, New York[1], the escarpment shapes in part the individual basins and landforms of Lakes Ontario, Huron and Michigan. In Rochester, New York, there are three waterfalls over the escarpment where the Genesee River flows through the city. The escarpment thence runs westward to the Niagara River forming a deep gorge north of Niagara Falls, which itself cascades over the escarpment. In southern Ontario it spans the Niagara Peninsula, closely following the Lake Ontario shore through the cities of St. Catharines, Hamilton and Dundas, where it takes a sharp turn north in the town of Milton toward Georgian Bay. It then follows the Georgian Bay shore northwestwards to form the spine of the Bruce Peninsula and Manitoulin Island, as well as several smaller islands located in northern Lake Huron where it turns westwards into the Upper Peninsula of northern Michigan, south of Sault Ste. Marie. It then extends southwards into Wisconsin following the Door Peninsula through the Bayshore Blufflands and then more inland from the western coast of Lake Michigan and Milwaukee ending northwest of Chicago near the Wisconsin-Illinois border.

As natural gas companies prepare to prospect in northern Michigan, experts are warning landowners to be careful about selling off mineral rights.
When the state took in an all-time record $178 million in a mineral rights auction back in May, it became apparent that natural gas companies see new opportunities in a shale formation that lies like a bowl under much of northwest-lower Michigan.
Up until May gas companies had been offering landowners around $150 per acre for mineral rights, but when bidding against each other for the right to drill on state land, the companies were willing to pay far more — an average of about $1,500 per acre. One parcel in Charlevoix County went for $5,500 per acre.
