This week’s episode of our YouTube tour of the PAD&W takes us to the section of line near Round Lake, MN (MP 89.5). After looping around a small lake and going through a double-trestle switchback, the grade continues to ascend along the northern face of a ridge. The engineering work is again heavy, with several cuts, a high embankment and a long, dark 300-foot rock cut. The views are spectacular.
