For more than 9,000 years, Teton Pass and the Trail Creek area served as a natural travel corridor between Jackson Hole and eastern Idaho. Early Indian groups used the route to reach hunting and plant gathering areas in Jackson Hole, and later trappers and explorers made Teton Pass the main corridor into the region. Historic documents record John Hoback, Jacob Reznor, and Edward Robinson leading Wilson Price Hunt and a party of Astorians over the pass in 1811 on their way to the Pacific Northwest, and Jim Bridger guiding William Reynolds of the Topographical Engineers over it in 1860 in search of a suitable railroad route. In the early 1880s, the first homesteaders began crossing into Jackson Hole, and in 1886 Joe Enfanger and Adolf Miller drove the first horse-drawn wagon over the pass, a journey that then took about two weeks. In the late 1880s, mail service from Victor, Idaho, to Jackson Hole began by horseback, wagon, ski, and snowshoe. After the Oregon Short Line Railroad spur reached Victor, Idaho, in 1912, increased tourist and freight traffic into Jackson led to the construction of road houses between Victor and Wilson where passengers and livestock could rest. Beginning in 1913, the Forest Service graded the first roadway up the pass from Wilson, improving on the wagon road. The old pass road, first widened in 1928, remained in use until 1969, when the present highway over Teton Pass was completed. Teton Pass was the most important access linking Jackson Hole with the rest of the world, and the wagon route carried people, household goods, mail, and cattle until the Old Pass Road replaced it; the History Trail follows that earlier route and preserves evidence of Jackson's early history.
