1. There are 250 mountains to be climbed from Georgia to Maine.
2. The total elevation gain is 471,151 feet, an average of 3,000 feet every day. That's like climbing Mount Everest 16 times in a row from sea level.
3. A 2002 thru-hiker, Gary Monk, counted the white blazes <../hike/hike_info/markings.html> of the Appalachian Trail as he walked from home in Georgia to Katahdin, counting double blazes as two. The final count from his "five million steps" was 82,366 blazes, with 68.7 percent of them along the 53.7 percent of the Trail north of ATC offices in Harpers Ferry, W.Va.
