Simpson’s Hollow
To visit Simpson’s Hollow, where Mormon militiamen attacked and burned a U.S. Army wagon train in October 1857 during the bloodless Utah War, travel about 12 miles west of Farson, Wyo. on Wyoming Highway 28. A stone marker and two Bureau of Land Management markers, all on the north side of the highway, commemorate this spot on the Oregon-California-Mormon-Pony Express Trail. For more information on the trail and to see a marked stretch of it, stop also at the Pilot Butte interpretive site on the south side of the highway, about three-fourths of a mile west of the Simpson’s Hollow markers.
