Minnesota Power is designing and building the 224-mile (360 km), 500-kV Great Northern Transmission Line through some of the most extensive peat bogs found in the U.S.’s lower 48 states. More often suited for boats than trucks, the ground gives walkers a water-cushioned bounce as their footprints fill in with a tannin-stained brew. Some stretches of the project route — chosen based on local community input, in part because it would reduce landowner impacts — are so remote some of the project
