Several sources identify Warm Springs as a station and Gregory Franzwa specifically names Warm Springs as a Pony Express site. He locates it on the Seminoe Cutoff from the Oregon Trail. (NPS)

Bishop and Henderson, as well as the mail contract of 1861, identify Ice Slough or Ice Springs as a C.O.C. & P.P. Express Co. station between Three Crossings and Warm Springs. Other sources do not list the slough as a station, but they mention its nearly year-round ice as a well-known landmark. Franzwa locates Ice Spring and Ice Slough separately in his Oregon Trail maps, but he does not list either site as a Pony Express station. (NPS)
Three Crossings on the Sweetwater River, so called because the trail crossed the stream three times within ¼ mile. Located 14 miles from Split Rock Station and 12 miles from Ice Springs Station south of the Sweetwater River. A telegraph and stage station of the 1860′s, it was to this station in 1860 that Bill Cody, 15 year-old Pony Express carrier, rode from Red Buttes on the Platte, 76 miles away. There he found that the rider of the 85-miles stretch to Rocky Ridge had been killed.
From South Pass, the Pony Express Trail followed the Sweetwater River northeastward to Split Rock Station which was located 65 miles north of Rawlins on US287 heading for Lander. Located 12 miles from Plant’s Station and 14 miles from Three Crossings Station. The Station Tender was Plant or Plante. Split Rock Relay Station was a crude log structure with a pole corral and was located on the south side of the Sweetwater River.
Located 12 miles from Sweetwater Pony Express Station, 6 miles from Devil’s Gate Station and 12 miles from Split Rock Station about 400 feet south of the Sweetwater River. The Station Tender was Plant and was probably the same Plant who was Tender at Split Rock. Believed that Sweetwater and Plant’s Stations were abandoned and that two Station Tenders with the same name was further evidence of the abandonment of Plant’s Station.

This station was not mentioned in the 1861 Overland Mail Contract. Located 6 miles from Sweetwater Pony Express Station and 6 miles from Plant’s Station.
The Pony Express Route and the Oregon Trail are the same through this part of Wyoming. Split Rock Station and Devil’s Gate Station are located one “Oregon Trail Day” apart.
Located 12 miles from Horse Creek Station, 6 miles from Devil’s Gate Station and 12 miles from Plant’s Station on north bank of the Sweetwater River and just south of the old Emigrant Road. Independence Rock is about one mile west. (Expedition Utah)
Many sources identify Willow Springs as a station, including the 1861 Overland Mail Company contract. The Hendersons located this station approximately twenty-eight miles southwest of current-day Casper, Wyoming. According to the Settles, the site at one time consisted of a crude structure without a corral, and it served as a home station for stage lines and a relay station for riders. Franzwa notes Willow Springs in his Oregon Trail maps but does not specifically identify it as a Pony or stage station.
Located 10 miles from North Platte Station and 12 miles from Willow Springs Station about 200 feet southwest of the Red Buttes Oregon Trail Marker and south of the old Goose Egg Ranch house. Red Buttes Pony Express Station was located on a ridge overlooking the North Platte River at Bessemer Bend. Explorers, fur traders, mountain men and emigrants camped at this site. Although the main route of the Oregon Trail was located a few miles north of this site, many emigrant travelers crossed the North Platte River here for the last time on their trek to the west.
