Ute Trail, which runs along the north side of
Pikes Peak is believed to have first been a buffalo trail that delivered buffalo from the "milder winter pastures of the eastern plains" to the "lush, grassy" meadows of
South Park, Colorado during the summer months. Joel Palmer wrote in his 1847
Journal of Travels over the Rocky Mountains: "These (buffalo) paths are remarkable in their appearance, being about 15 inches wide, and four inches deep, and worn into the soil as smoothly as they could be cut with a spade."
Stephen Harriman Long wrote of his 1820s travel through the Pikes Peak region that Ute Trail was used by bison and Native Americans. For the
Utes, the trail and pass was used to transport salt from Bayou Salade, the salt valley of South Park, to Santa Fe and Taos for trade. Ute Trail became a wagon road in the 1860s providing transport to Leadville mining camp. Tourism began to be a major economic force in the late 19th century and towns along Ute Pass built cabins and hotels as a result. The pass at one time was used by stage coach and equestrian traffic. It is steep (7%) on the east side. ==Ecological system==
