Question: Blood Mountain is the highest peak on the Georgia section of a marked hiking trail in the Eastern United States that is about how many miles long?
Context: The Lone Star Hiking Trail (LSHT) is a hiking trail 96 miles long with an additional 32 miles of loop and crossover trails of "foot-path only" trails.  Located in the Sam Houston National Forest it is the longest continuous hiking trail in the State of Texas.  The trail starts just South of Richards, Texas and ends North-West of Cleveland, Texas. 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. Forellen Peak (9772 ft , "Forellen" is German and means "Trouts") is located in the Teton Range, Grand Teton National Park, in the U.S. state of Wyoming.  The peak is in the northern section of the range, and rises abruptly more than 2500 ft above Owl Creek.  Unlike the more impressive sections of the Teton Range to the south, Forellen Peak is subdued and the hike to the summit from the north is nontechnical, yet requires many miles of off-trail hiking.  Access is best via the Berry Creek trail which can be reached by hiking south from the John D. Rockefeller, Jr.  Memorial Parkway or by boat across the northern end of Jackson Lake. Coosa Bald, with an elevation of 4280 ft , is tied with Double Spring Knob as the tenth-highest peak in Georgia.  It is located in Union County and is the third-highest mountain in the county, behind Blood Mountain and Slaughter Mountain.  Coosa Bald is located in the Chattahoochee National Forest and its peak is crossed by the Duncan Ridge Trail, a trail that connects with the Benton MacKaye Trail and the Appalachian Trail. Meredith Hope Emerson (June 20, 1983 – January 4, 2008) was a 24-year-old woman who was murdered in January 2008 by drifter Gary Michael Hilton.  She was last seen alive hiking with her dog on Blood Mountain in northern Georgia on New Year's Day 2008.  Witnesses claimed to have seen her with an older man on the Spur Trail connecting the Appalachian Trail with the Byron Herbert Reece Parking Lot (Georgia).  When she did not return home on January 2, 2008, her friends began to search for her, without success.  Her dog, Ella, was found on January 4, 2008, in Cumming, Georgia, approximately 60 miles away. Blood Mountain is the highest peak on the Georgia section of the Appalachian Trail and the sixth-tallest mountain in Georgia, with an elevation of 4458 ft .  It is located on the border of Lumpkin County with Union County and is within the boundaries of the Chattahoochee National Forest and the Blood Mountain Wilderness.  There are several waterfalls, hiking trails and other recreational areas in the vicinity. Hiking trail of the Piusa River of RMK (State Forest Management Centre) is a 15 kilometre long hiking trail past Vana-Vastseliina castle ruins along the primeval valley of the Piusa River up to Lindora village in Estonia.  The trail is marked by wooden signposts and information boards that introduce the sights.  There are two campfire sights on the trail supplied with barbecue grills and with the possibility of camping.  There are two picnic tables with shelters and a dry toilet.  The hiking trail is situated on Piusa River Valley Landscape Protection Area and among the most interesting sights on the trail are castle ruins, sandstone outcrops Härma Mäemine wall or Keldri wall (highest sandstone outcrop in Estonia), Härma alumine wall or Keldri wall and several old mill places.  There are altogether 12 sandstone outcrops on the hiking trail. The Alaska Basin Trail is a 7.5 mi long hiking trail in Grand Teton National Park and Bridger-Teton National Forest in the U.S. state of Wyoming.  The trail begins at a junction on the Death Canyon Trail near the Death Canyon Barn and climbs steeply to Static Peak Divide.  From the divide, the trail soon splits with a western branch descending into Alaska Basin and the eastern trail (also known as the Alaska Basin Shelf Trail) continuing north to junction with the Teton Crest Trail.  There are no camping zones on the trail within Grand Teton National Park, however in National Forest lands within Alaska Basin, camping is permitted anywhere more than 200 ft away from lakes, though no open fires are allowed.  The Alaska Basin Trail is oftentimes used by climbers attempting to make ascents of Buck Mountain and Veiled Peak. Slaughter Mountain, with an elevation of 4338 ft , is the ninth-highest peak in the U.S. state of Georgia.  It is located in Union County, Georgia and is the second-highest mountain in Union County.  Its nearest neighbor is Blood Mountain, the highest peak in Union County and fifth-highest in Georgia. Thru-hiking, or through-hiking, is hiking a long-distance trail end-to-end within one hiking season.  In United States, the term is most commonly associated with the Appalachian Trail (AT), the Pacific Crest Trail (PCT), and the Continental Divide Trail (CDT), but also refers to other end-to-end hikes.  Other examples include the Te Araroa Trail in New Zealand, the Camino de Santiago in Spain, the Via Francigena in France and Italy, the Lycian Way in Turkey, the Israel National Trail, and the Great Divide Trail (GDT) in Canada.  Thru-hiking is also called "end-to-end hiking" or "end-to-ending" on some trails, like Vermont's Long Trail or New York's Long Path and Northville–Placid Trail.  Section hiking, on the other hand, refers to hiking a trail one section at a time, without continuity and not necessarily in sequence with the other sections.
