In 1865 a treaty required the Indians to move to the Uintah reservation, which Brigham Young had established in 1851. Lt. Pardon Dodds, the first official Indian agent, built a log cabin and fort in 1867 on the upper Duchesne River one mile above Tabiona, and soldiers used it during Indian uprisings. The agency moved to Fort Duchesne in 1868. Later the fort burned, and rocks from the chimney, which stood as a landmark for many years, were used to build this monument.
