Alvar on the Bruce Peninsula

I took this photo on the Bruce Peninsula in Canada, a finger of land that juts into Lake Huron. Here and on the Door Peninsula in Wisconsin these peninsulas are of limestone and sometimes fossils may be found embedded in the rock. The tree pictured is a cedar. Many shipwrecks lie under the waters surrounding these peninsulas since the waters are trecherous. The Door Peninsula was so named because sailors called it "Death's Door."

I like this photo so well I asked my publisher to use it for the cover of my book, The Dynamic Great Lakes.
