Question: How high is the mountain that is at the start of the Appalachian Trail?
Context: North to Maine is a 2009 play by American playwright Brenton Lengel.  It is the first play ever written about the Appalachian Trail and the thru-hikers who walk it.  The play is sprawling and epic, with scenes taking place over the course of several months and many states, culminating with the ascent of Katahdin, the northern terminus of the Appalachian Trail.  The work has received several awards, honors, and sponsorships and is supported by the Appalachian Trail Conservancy and the New York–New Jersey Trail Conference. Warren Doyle is a hiker, and supporter of the Appalachian Trail.  He holds the informal record for the hiking the most miles on the trail (36,000 miles).  He is the founder of two organizations dedicated to the trail: the Appalachian Long Distance Hikers Association, and the Appalachian Trail Institute.  He remains the Director of Appalachian Trail Institute. The Appalachian Trail Metro-North Railroad station serves campers and hikers destined for the Appalachian Trail in Dutchess County, New York via the Harlem Line.  It is the only rail station directly located on the Appalachian Trail.  Trains stop at Appalachian Trail on Saturdays, Sundays, and holidays only.  The Connecticut State line is about 7 miles from the station.  It is 65.9 mi from Grand Central Terminal and travel time to Grand Central is approximately 1 hour 52 minutes.  This station is the northernmost station in the Zone 8 Metro-North fare zone.  There are no transportation connections via bus or taxi, but NY 22 is only steps away from the station. Springer Mountain is a mountain located in the Chattahoochee National Forest on the border of Fannin and Gilmer counties.  Located in the Blue Ridge Mountains in northern Georgia, the mountain has an elevation of about 3782 ft .  Springer Mountain serves as the southern termini for the Appalachian and Benton MacKaye trails. The Tuscarora Trail is a 252 mi long bypass route of the Appalachian Trail that passes through the US states of Virginia, West Virginia, Maryland, and Pennsylvania.  In the south, the Tuscarora begins where the Appalachian Trail intersects Skyline Drive in Shenandoah National Park in Virginia.  In the north, it rejoins the Appalachian Trail at the top of Blue Mountain just west of the Susquehanna River and Harrisburg, Pennsylvania, creating a 435 mi circuit known as the Tuscalachian Loop. The Appalachian Trail Conservancy (ATC) (formerly Appalachian Trail Conference) is a nonprofit organization dedicated to the conservation of the Appalachian Trail, a route in the eastern United States that runs from Maine to Georgia.  Founded in 1925, the ATC works to protect the trail's 2189 mi , 250,000 acre (1,000 km²) greenway, and coordinates the work of some thirty hiking clubs performing trail maintenance. The Appalachian National Scenic Trail, generally known as the Appalachian Trail or simply the A.T., is a marked hiking trail in the Eastern United States extending between Springer Mountain in Georgia and Mount Katahdin in Maine.  The trail is about 2,200 miles (3,500 km) long, though the exact length changes over time as parts are modified or rerouted.  The Appalachian Trail Conservancy claims that the Appalachian Trail is the longest hiking-only trail in the world.  More than 2 million people are said to do at least one day-hike on the trail each year. The Hundred-Mile Wilderness is the section of the Appalachian Trail running between Abol Bridge just south of Baxter State Park and Monson in the state of Maine.  It is generally considered the wildest section of the Appalachian Trail, and one of the most challenging to navigate and traverse.  This section of the A.T. is crossed by several logging roads and is maintained by the Maine Appalachian Trail Club.  It consists of a small corridor of protected wilderness surrounded by large tracts of public and private land controlled by paper companies.  An increasing amount of the adjoining lands are being protected by groups like the Appalachian Mountain Club and the Nature Conservancy. The Appalachian Trail Museum is located in Pine Grove Furnace State Park near Gardners, Pennsylvania, United States, and commemorates pioneer Appalachian Trail builders and hikers including those in the Appalachian Trail Hall of Fame.  Artifacts include a 1959 trail shelter from Peters Mountain and vintage hiking equipment such as canes. The Appalachian National Scenic Trail spans fourteen U.S. states during its journey that is 2189 mi long, including Georgia, North Carolina, Tennessee, Virginia, West Virginia, Maryland, Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, Vermont, New Hampshire, and Maine.  It begins at Springer Mountain, Georgia, and follows the ridgeline of the Appalachian Mountains, crossing many of its highest peaks and running with only a few exceptions almost continuously through wilderness before ending at Mount Katahdin, Maine.
