Cameron was named for the pioneering Cameron family. The settlement was originally known as Bear Creek. Addison Bovey Cameron and his brother James took up desert claims here in 1886. Addison Cameron had the first post office in his home from 1890 to 1893. Later he and his wife, Josie, had a store and post office on the ground floor of a building and a dance or community hall on the upper floor. In 1919 the Cameron store building was purchased by Frank Falbaum, who moved it six miles down the road to take advantage of the highway business generated by tourists traveling between Ennis and Yellowstone National Park. This angered Bear Creek settlers, and for years none of them would trade at the Cameron store.
The ranchers who now use the post office as headquarters have rich hay and pasture lands spreading up to the foot of Sphinx Mountain (elev. 10,860 ft.). The mountain was officially named by geologists because of a supposed resemblance to the Great Sphinx of Giza, but natives affectionately call it "Old Red" because of the beautiful red rock cliffs that glisten in the sunset.
