West of Register Cliff, the landscape changed and presented new challenges for emigrants. Limited water and rugged terrain made travel more difficult as they crossed the plains of southern Wyoming toward Fort Bridger, the next major supply point 368 miles away. Register Cliff became one of the best trail registers in the desert, where countless emigrants inscribed their names, dates, places of origin, and messages into the sandstone cliffs. The earliest inscriptions came from fur traders and trappers who passed through the region in the early 1800s. In the 1870s and 1880s, ranchers and homesteaders moved into the area. Charles A. Guernsey, for whom the town of Guernsey is named, arrived in June 1880 trailing cattle from Colorado. The Guernsey Cattle Company was established the following year with 999, or Three-Nine, as its brand. Guernsey established his ranch at the base of Register Cliff and continued to operate it until 1926. Later the Henry Frederick family settled in the area, and ranching continues there today.
