To provide educational background for this new series of Driftless films and lessons, we’ve provided online viewing of our Mysteries of the Driftless documentary that you’ll find below. As you watch the film, you’ll discover what strange forces saved this one isolated section along the Upper Mississippi River from the repeated crushing and scouring effects of glaciers during the last two million years. You’ll also find out what pre-ice age throwbacks survived here in this unique geologic refuge that holds more Native America effigy mounds, petroglyph caves, strange geology features, and rare species than anywhere in the Midwest. But you’ll also discover that there’s much to still be explored and learned within the Driftless. One film simply isn’t enough.
