THE SENEY SWAMP
The Seney Swamp is a sandy, wet, flat area in the central UP. This area was once
under the waters of Glacial Lake Algonquin, and
hence is very flat and wet.
In some areas, small sand dunes (see below) have formed on
the lake floor. The sand became mobile at times in the geologic past (probably a few
thousand years ago) when it was a bit drier.
The images below show what this area looks like.
Unusual or extreme habitats in Michigan include the "big prairie" area in
Newaygo County, a region of loose, sandy soils and more xeric vegetation; the Seney
Wildlife Refuge, an unusually large bog expanse in the Upper Peninsula; and the exposed
mountain tops in portions of the Keweenaw Peninsula and Huron Mountains. In one way or
another, these habitats are examples of the way local environmental factors may cause a
vegetation assemblage that is considerably different from the regional pattern.
Where IS the Seney Swamp? It is located west of Seney! In fact, the long,
straight, flat, extremely monotonous stretch of M-28 west of Seney, which crosses the
swamp, is called by many the infamous "Seney Stretch". It is about 30
miles of woods, water, swamp, and not much else.
