By 1850, the Oregon-Mormon Pioneer-California trail system had developed almost as many shortcuts as there were wagon masters. The emigrants called these shortcuts "Cutoffs."
The Sublette Cutoff was one of the earliest shortcuts. It made an almost direct east-west connection between South Pass and the Brear River, avoiding a southern loop to Fort Bridger. Most of the emigrants avoided it, but the Forty-Niners used it regularly. The Sublette Cutoff saved 70 miles or about three days travel time.
The Sublette Cutoff is well-marked and crosses BLM-managed public lands for much of its distance.
