Dahlen Esker

Eskers are basically river channels that formed under the glacial ice during the last ice age. When the ice melts the river deposits fall to the surface and leave inverted river channels in the shape of long, sinuous ridges that snake across the landscape. The Dahlen Esker rises about 50-80 feet above the surrounding (flat) farmland and is one of the best examples of eskers in North America. It is about 4 miles long and 400 ft wide. The best access is through township line roads that are muddy and steep in some places. Contact the ND Geological Survey for directions.

I came out here with a geology field trip, and it is really in the middle of nowhere. But it is an excellent example of an esker. The Dahlen Esker is located about an hour west of Grand Forks, ND. If you happen to be driving Hwy 2 between Grand Forks and Minot (or Devils Lake), it isn't far off the highway. Unless you have a liking for geology or hiking, there is no reason to go here. The esker has native prairie grasses growing on it in many places and is a nice place to hike - but there isn't any shade.
