And now it's time to do something I've wanted to do ever since I arrived in Seattle: rank the high points by difficulty!
I'd come across the Martin Classification of state high point difficulty while planning my trip, but it didn't quite satisfy me. For one, it only considers the easiest route to a high point's summit, which leads to sizeable mountains like North Carolina's Mt. Mitchell and New Hampshire's Mt. Washington being ranked in the easiest class. While technically correct, in that those summits can both be accessed by walking less than 0.2 miles, such a ranking is useless to one who intends to hike those high points from their base. What's more, both those mountains have "standard approach" trails that could easily be incorporated into the ranking alongside the drive-up routes.
And second, Martin's classification takes little account of the technical difficulty of a route; instead, it relies almost exclusively on elevation gain and trail length. This also leads to some odd rankings, in my opinion (for instance, the gentle stroll up Black Mesa, OK is ranked a class above the rough, rocky trails on Mt. Frissell, CT and Mt. Mansfield, VT). While an experienced mountaineer considering the glaciated Western high points might not care whether the approach is Class 1 or Class 2 terrain, the distinction matters to casual hikers, not to mention those with mobility issues, acrophobia, and/or small children in tow. And regardless of ability, many people would find a 7-mile hike easier than a 4-mile scramble of equal elevation gain (just ask anyone who's done both Mt. Marcy and Katahdin's Knife-Edge which was harder).
Thus, I've put together my own ranking of the highpoints I've climbed, available here as a list and on my homepage (where I control the backend code) as a sortable table. The standard route up each high point (as selected by me) is listed below, as are any alternate routes of sufficiently different character (again, my judgement call). Starred routes are featured in this blog. I intend to complete this ranking as I continue highpointing, so check back for additions.
