In my Minnpost column this week, I wrote about Platteville Limestone, the Twin Cities' earliest construction stone. The gist is that it's a great thing to spot as a clue to the age of the urban landscape, and I wanted to offer some examples for you from a recent wander I took around St. Paul's Ramsey Hill, Irvine Park, and West Side.
Here you go!
