    Okay, here are the calculations using 0.5 miles as the limit rather than 1.0 miles. One thing that is clear to me after looking at these is that after the top 20 or 30, things start to look pretty similar. I think this is more interesting as a discussion piece (just an addition to what's already been discussed here), but I had a good time running through all of the calculations with my elevation data. It's kind of fun to see the numbers. Here we go:

    Section 1 from 1865.5 to 1866.0 with 1017 change -- Pinkham Notch to Wildcat E (2000' in 1.5m)
    Section 2 from 1794.3 to 1794.8 with 934 change -- Asquam Ridge Trail to Kinsman Notch (2180' in 1.7m)
    Section 3 from 1824.2 to 1824.7 with 896 change -- Galehead to South Twin (1130' in 0.8m)
    Section 4 from 1821.2 to 1821.7 with 875 change -- Northbound from Mt Garfield (970' in 0.6m)

    Section 7 from 1869.9 to 1870.4 with 846 change -- Carter Notch to Carter Dome (1530' in 1.1m)
    Section 8 from 1934.5 to 1935.0 with 812 change -- South Arm Rd to Old Blue (2180' in 2.6m)
    Section 9 from 1790.4 to 1790.9 with 801 change -- South Peak Moosilauke (total, 2920' in 3.0m)

    ME: 26
    NH: 22
    VT: 5
    MA: 4
    VA: 4
    NC: 3
    TN: 3
    NY: 3
    CT: 2
    PA: 2
    NJ: 1

    -ME and NH get all of the top 20.
    -Mile for mile, NH wins. ME gets second.
    -Roan Mountain in two sections gets 56 and 69
    -Bly Gap, Blood Mountain, Albert Mountain, and several other notables were missed because the steepest parts of the climbs were less than 0.5 miles long.

    This is a big old dump of data. I'll clean it up sometime and make it easier to navigate. For now, my eyes are telling me to stop looking at the computer screen

    Thanks Guthook. This confirms for me that the people who build and design trails in New England are sadistic ************s.

    It is surprising how different climbs impact different people. I actually did exceedingly well on each of these climbs (except Stratton, which didn't exist when I went through in the 70's). The climb of South Kinsman still rates as my hardest climb, despite the nice cool temperature as the first climb of the day. I found it quite a bit harder than going up to Liberty Spring later that afternoon.

    I think you are remembering the north side of Bear Mountain in Connecticut. It was just south of Sages Ravine and indeed it is quite steep and rocky. I nearly had a bad fall coming down that rock face. The only thing that saved me was my trekking pole. Bent it pretty good.

    To calculate grade, you take the vertical distance divided by the horizontal distance and multipy by 100 to get a percent. For example, if you climb 1000 feet in 1000 feet (such as up the side of a building) the grade would be 100% If you climb 0 feet by any distance, the grade is 0 %

    By doing that calculation I get the following grades for the first 5 sections on the post #121 list:

    25.25 %
    24.28 %
    26.75%
    31.04 %
    28.68 %

    Going by this method, the Section 4 from 1821.2 to 1821.7 with 875 change -- Northbound from Mt Garfield (970' in 0.6m) is worse then the first ones on the list.
    The AT - It has it's ups and downs...

    Absolutely agree. And there are a lot of factors that go into the climb that aren't reflected by the elevation profile. For instance, going up Mahoosuc Arm, you're on a pretty solid slab of rock, rather than dirt or stairs. And then there are the little ups and downs that don't register (I'm thinking of the NJ/NY border, which looks more or less flat on the profile, but has tons of little ups and downs). Temperature, humidity, energy level... all of those things could combine to make a nearly flat trail harder than Wildcat or Carter Notch... but it's still fun to play with the climbs on paper like this

    Right. The way they're sorted here is by grade of the steepest half mile section-- the full climb isn't taken into account. Notice that every section first lists exactly one half mile, then the elevation change for that half mile. Like I said before, if you narrow the distance enough, a single stair can be listed as the steepest section of the entire trail.

    -ME and NH get all of the top 20.
    -Mile for mile, NH wins. ME gets second.
    -Roan Mountain in two sections gets 56 and 69
    -Bly Gap, Blood Mountain, Albert Mountain, and several other notables were missed because the steepest parts of the climbs were less than 0.5 miles long.

    This is a big old dump of data. I'll clean it up sometime and make it easier to navigate. For now, my eyes are telling me to stop looking at the computer screen
    Thanks for taking time to crunch these numbers. Interesting. Take a break.
    I bet you're curious as to what the steepest 2 mi section is. I know I am.

    Haha. Maybe a little later :-) I'm actually pretty curious about what the steepest 2184 mile section is...

    If you can sum the total elevation gain for the AT, you can determine the average grade for the trail which would be an indication of it's overall difficulty. But if you do that, then we're all going to want to know that number for each state and then between each town and so on and so on...
    The AT - It has it's ups and downs...

    Just curious, does this data include the recent reroutes and switchbacks on Roan mountain? They have made it much easier now than it used to be.
    I thought that climb past Wilbur Dam road was surprising--now I know why!!

    It's all downhill from ME . . . SOBO is obviously easier

    North of Wilbur Dam has recently added switch backs. I'm not sure if they were taken into account.

    Data for Springer to Damascus is all from October 2012, so it might miss those switchbacks. Do you know when they were added?

I think this is more interesting as a discussion piece (just an addition to what's already been discussed here), but I had a good time running through all of the calculations with my elevation data. It's kind of fun to see the numbers. Here we go:

    Section 1 from 1865.5 to 1866.0 with 1017 change -- Pinkham Notch to Wildcat E (2000' in 1.5m)
    Section 2 from 1794.3 to 1794.8 with 934 change -- Asquam Ridge Trail to Kinsman Notch (2180' in 1.7m)
    ...

    guthook good job.

    what is the source of your elevation data?

    is your GPS track data (lat,lon) available on-line?

    I'm also surprised to not see the Priest climb on this data sheet....or did I miss it?

    Wilber Dam Rd to the top of the Ridge was completed with switchbacks several years ago to 10% or less with hardcore. Hughes Gap to Ash Gap was finished with Switchbacks a few years ago with Hardcore and other groups. It is now 10% or less. Ash Gap needs 4 short switchbacks installed and 3 others to be tied in to complete this section also. It is scheduled to be completed during Trail Days this year. When finished Ash Gap to Roan Mtn will be 12% or less. The distance from Hughes Gap to the top of Roan Mtn will more than double when finished to more than 5 miles.

    Hey Chinook,

    The source of the data is from hiking the trail with GPS from Springer to Damascus, and Delaware Water Gap to Katahdin between October 2011 and August 2013. The Damascus to DWG section is from the ATC's official GPS track of the trail (2007), with all missing elevations filled in from Google Earth, plus all of the GPS elevation checked against Google to ensure there weren't any major errors.

    I don't have my data online, although the ATC track is mostly right, just missing relocations since 2007. Send me an email, though, if you'd like a copy of some of the GPS data. guthookhikes at gmail

    Gut hook,
    I bought you Applacian Trails Guide for iPhone, and was wondering if the data for the app is the same as what you are discussing in this thread?
