Halfway to the North Pole - Door County, WI

We were driving on the Lake Michigan (east) side of Door County and saw a sign for a highway marker.  We pulled in and saw this sign.


We were 1/2 way between the Equator and the North Pole @ 45 degree north latitude.  Pretty impressive, I thought!
This is a Limestone outcropping with a thin layer of soil on top of the rock so roots have no place to go. In a previous blog I showed trees toppled over (just before we got there) due to high winds.  
Because of so much rock, the water table is protected as well as other being other environmental impacts.  This rock layer runs from Minnesota to Niagra Falls, NY.

I also saw that sign when we first got to Lake Michigan last month.

That is a very interesting sign. We see some very interesting alpine trees with roots combined with rocks when we drive over Yosemite. Thanks for advertising on my blog.
