Interstate State Park with Dogs of MSP

  • Interstate State Park 307 Milltown Road Taylors Falls, MN, 55084 United States (map)


Join Dogs of MSP and Hiking The North as we explore Interstate State Park and discover some of the worlds deepest potholes! Your pup will have fun exploring different trails and meet other furry friends! The Glacial St. Croix left more than a wide valley and high cliffs to impress visitors. It also drilled holes in the basalt, some of them so deep that it’s hard to see how water alone could form them.  Hiking The North will guide you through a 5 mile hike on several trails. We will start this journey at 10am and will end at 12pm! Trail is from easy to moderate. Bring water, snacks, and backpack. Dress appropriately for the weather!

About 1.1 billion years ago, earthquakes erupted from Taylors Falls to Lake Superior and caused at least 10 different lava flows. The hardened basalt rock from these lava flows partly formed the Dalles of the St. Croix and the bottom of the river. From 530 million years ago up until 70 million years ago, the state was washed by advancing and retreating seas. Evidence of these ancient seas is revealed in the sedimentary rocks and formations found in the park. These rocks contain fossil remains of ancient animals, evidence of various creatures, and ripple marks left in stone by the now vanished seas.

There have been many different St. Croix Valleys through the ages. The first formed about 70 million years ago and current valley formed about 10,000 years ago. A glacier formed both Glacial Lake Duluth, now Lake Superior, and Glacial Lake Grantsburg, now extinct. Glacial Lake Duluth was much larger than modern day Lake Superior. As this giant body of ice thawed, its meltwaters roared south to carve out the broad valley of the St. Croix. Only very resistant basalts were able to partially withstand the torrent, resulted in the dalles, potholes, and cliffs we see today.
