The Gunflint and Lake Superior Railroad was a logging line operated by the Pigeon River Lumber Company from 1902 to 1909. It connected to the Canadian Northern Railway Duluth Extension/North Lake Subdivision (ex-Port Arthur, Duluth and Western Railway) at Milepost 79. It travelled six miles from the Ontario side of Gunflint Lake into Minnesota passing Crab and Whisker Lakes to near Topper Lake.

This video covers the approaches and the remains of a former large corduroy wood trestle that was used by the line to climb the ridges south of Gunflint Lake. It was damaged in a 1999 windstorm and then burned by the 2007 Ham Lake Fire. The logs continued to smolder throughout the winter, so in March 2008 the US Forest Service was forced to dynamite the trestle to extinguish the fire. Be sure to view the 1997 video to see what it looked like before its demise Gunflint & Lake Superior Railroad MP 2.4-2.5 (Corduroy Trestle 1997) https://youtu.be/nHhwDx3yLWw
