The White Mountain National Forest includes over 100 miles of which marked hiking trail?
Appalachian Trail 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.
Wrangell–Saint Elias Wilderness Wrangell–Saint Elias Wilderness is a wilderness area in Alaska, United States. At 9078675 acre , it is the largest designated U.S. Wilderness Area, and lies within Wrangell–St. Elias National Park and Preserve, the largest national park in the United States. It is a land of remote valleys, wild rivers, and a fabulous wildlife population that includes Dall sheep, grizzly bears, black bears, coyotes, bison, caribou, wolverines, moose, beavers, mountain goats, gray wolves, red foxes, and marmots. In the north the glaciated peaks drop to tundra and boreal forested uplands. In the south massive glaciers spread from the mountains almost to the Gulf of Alaska. Several trails provide foot or horse access, but large braided rivers often stop progress unless a packraft is used. The classic route across the wilderness links the gold-rush era settlement of Chisana with the copper-mining era community of McCarthy, via 100 mi of tundra, trails and gravel bars. Unmaintained trails lead through spruce forests near Chisana, across high tundra plains to the White River, below 16000 ft mountains over Skolai Pass, and into the Chitistone Gorge and Canyon with waterfalls to 1500 ft high. Mosquitoes are thick in the low country during the summer, and enough snow accumulates in the high country to make avalanches a year-round danger.
