We have the hardest mile thread going, but what about the steepest mile? Meaning net elevation gain or loss (depending on direction) over a full mile.
Looking at the few maps I have (GSMNP, most of VA, VT/NH and ME), there appears to be quite a few 1000'/mile sections, and maybe a couple of 1200'/mile sections. I hiked a few of those on a recent ME section hike, and they were not as bad in person as they appear on a profile.
Their are a few short sections that are steeper, a full mile worth, I can't find.
