Seminoe Cutoff

The Seminoe Cutoff leaves the main branch of the Oregon Trail about seven miles west of Ice Slough and three miles southeast of Sweetwater Station, Wyo., and heads west for 35 miles before rejoining the main branch of the trail. At Immigrant Springs, halfway along the route, lies the grave of Sarah Thomas, who died in 1854. The cutoff rejoins the main trail west of the Ninth Crossing of the Sweetwater and a few miles east of South Pass. The cutoff is on public land. Travel only in good, dry weather in a high-clearance, four-wheel-drive vehicle. For maps and directions, contact the Lander Field Office of the Bureau of Land Management, 307-332-8400,
