Your licensed boat pilot and tour guide will point out the unique rock formations that were left behind as the glaciers retreated thousands of years ago. Among the most outstanding formation is the huge stone cross for which the St. Croix River was named. "St. Croix" means Holy Cross.
Other sites that can be seen from the boats include: the world's largest glacial kettles or "pot holes", Lion's Head, Turk's Head and the highlight of the boat tour, The Old Man of the Dalles - the most outstanding natural rock face you'll ever see.
Eagles and other wildlife are seen on 75%+ of boat trips. It is a great way to spend the day or the hour on the river.
