which mountain man rediscovered south pass and brought back important information about this trail
Jedediah Smith Jedediah Strong Smith (January 6, 1799 – May 27, 1831), was a clerk, frontiersman, hunter, trapper, author, cartographer, and explorer of the Rocky Mountains, the North American West, and the Southwest during the early 19th century. After 75 years of obscurity following his death, Smith was rediscovered as the American whose explorations led to the use of the 20-mile (32 km)-wide South Pass as the dominant point of crossing the Continental Divide for pioneers on the Oregon Trail.
Appalachian Trail On October 7, 1923, the first section of the trail, from Bear Mountain west through Harriman State Park to Arden, New York, was opened. MacKaye then called for a two-day Appalachian Trail conference to be held in March 1925 in Washington, D.C. This meeting inspired the formation of the Appalachian Trail Conference (now called the Appalachian Trail Conservancy) (ATC).[10]
