Door County Geology


The topography of the peninsula is characterized by dolostone bedrock that is painfully close to the surface.

At The Platz the bedrock is alternately within a foot of two of the surface or as much as eighteen feet below the surface.  Sometimes it is at the surface.  A couple of miles away the Niagra Escarpment is above the surface.

This cedar is growing from the exposed face of a cliff and is likely thousands of years old.








If you pay attention to the scenery found in the countryside you might spy ancient stone fences  constructed of chunks of the bedrock that have worked their way to the surface due to the freeze/thaw cycle of the seasons.

Upon careful examination you can  often find the scars of plows on the surface of these stones.

Just imagine the back-breaking labor that was expended gathering those stones a hundred or more years ago.

There were no skid-loaders back then.
