A tight shot of the middle falls at Gooseberry Falls State Park reveal a variety of colors. Tannins from decaying vegetation cause the color of many North Shore rivers, including the Gooseberry River, to appear root beer-colored. Derek Montgomery for MPR News

Amity Creek empties into what locals call "The Deeps" on April 3 in Duluth. Not far downstream, Amity Creek merges with the Lester River before emptying into Lake Superior. "The Deeps" is a popular and sometimes dangerous swimming hole during the summer. Derek Montgomery for MPR News
The portion of the Brule River within Judge C.R. Magney State Park featuring the Devil's Kettle waterfall remains covered in ice on April 9 near Hovland, Minn. Steeped in mystery and lore for many years, the Brule River splits at this location, with one potion continuing to flow toward Lake Superior and another portion descending into a hole where it seemingly disappeared. The mystery of where all this water went was <a href="https://www.mprnews.org/story/2017/02/28/hydrologists-solve-minnesota-devils-kettle-falls-mystery">solved in 2017</a> when a groundwater hydrologist from the Minnesota Department of Natural Resources decided to look into the mystery by measuring the water flow above and below the falls. It turns out, the measurements were the same, meaning the water was reappearing right at the base of the falls. Derek Montgomery for MPR News

From the streams that cascade through Duluth to mighty High Falls on the Canadian border, the waterfalls of Minnesota's North Shore are putting on a show.

Fueled by snowmelt and free of winter's icy cloak, the rivers that tumble toward Lake Superior are near the peak of their annual spring spectacle.

Photographer Derek Montgomery ventured along Highway 61 to capture images from a few of the roaring falls.
