The Dalles of St. Croix
|Photos by Ben Prepelka
Formed by retreat of the last continental ice sheets, the massive Lake Duluth became filled with glacial melt, forming a shoreline 400 feet higher than today's Lake Superior. Eventually ice dams broke, sending its charging waters through layers of ancient volcanic rock. Wisconsinís Interstate Park embodies this ancient event and offers close up views of a steep-walled gorge of the Dalles of the St. Croix River. Carved into a series of terraces, sand and gravel were caught in river eddies, hollowing out glacial potholes on both sides of the river. Across the St. Croix at Minnesota's Interstate Park, the Glacial Gardens section contains more than 80 potholes. One, called the Bottomless Pit, is 10 feet wide and 60 feet deep.
