Keweenaw Wall or the "Natural Wall" is a geological anomaly which is located in Michigan's Upper
 Peninsula and located north of Lake Linden, Michigan in the Keweenaw Peninsula. It is a relatively
 rare formation of stone that was created by volcanic activity long ago along with actions described as
 erosion during the "Jacobsville sedimentation" period. The result is a very unusual rock or stone
 formation that appears to be granite in appearance on one side of this wall, and appears completely
 different on the other side, where a more sandstone - looking appearance of rock shows on the
 opposite side of this unusual formation. All of the compressional tectonism which occured during the
 time which the Keweenaw Fault was forming, has offered up one of nature's bizarre looking and most
 unusual and obscure stone formations.

 

 

 

 This site was established to provide basic background information on the author's interpretations of
 the wall formation itself, the terrain in which it's located on and it's location, how to get there and
 provide additional photographic documentation.
 

The side of the wall as you approach it along the river bed - looks smoother in appearance.

This side of the wall has the appearance of granite and is located a few feet off of the creek bed and the wall itself rises possibly 40 feet high or more. It protrudes out of the side of the ravine which is roughly at a 45 degree angle.

Another angle of the wall upon approach which has an ominous look as it hangs over the river bed.

This rock anomaly also could have covered the entire ravine across to the other side as you will notice other fragments of stone which have a similar size and appearance that are embedded in the opposite side of the ravine.

The other side of the wall has a definite look of sandstone to it. Unlike the opposite side which looks more like a harder and smoother type of stone

Visiting this side upon closer inspection shows a more "rippled" look to the finish. Could years of erosion from constant water pressure have etched this into the rock?


 

 Getting there is based on the info provided here and
 is based on the image maps provided below. It is
 advised you also cross reference these maps by down-
 loading your own similar satellite maps off of your
 favorite search engine by typing in the search term
 "Lake Linden Michigan" to refer to and compare. Use
 the river bed and follow it at your discretion and be
 certain to have the proper footwear based on the
 weather - no sandals or tennis shoes!
 Dress accordingly . . . if exploring during hotter and
 more humid weather, no jacket required, however
 keep the mosquitoes and other critters in mind. If you
 decide to venture in the fall months, grab a hat and
 jacket. Recommended footwear should be worn, like
 a waterproof insulated hiking boot with sturdy soles.
 Be ready to jump across rocks and possibly step into
 pools of water or mud.

 

 The darker looking rift (below Old Colony Rd.) is the ravine where the wall is located. Note
 the rail grade you'll encounter which will be on your left, coming from Angman rd.

 

 Photos in the galleries here, were taken on the first of November when no foliage was on
 the trees to allow for better pictures. Many shrubs and small trees are clustered around
 the rock wall during the summer months and can camouflage or obscure the site. If you
 decide to investigate during spring, be ready for alot of mud, water and run-off, if you
 go in during the summer, the river bed may be lower during a dry spell. If you venture in
 after a day's worth of rain, there will be higher water running through the ravine at that
 time so consider a few factors when planning to visit, if you decide to go. And enter by
 using the creek bed . . . don't violate any trespassing laws.
