Acton State Historic Site is Texas's smallest historic site with a total of .01 acres. The site is the burial ground of Elizabeth Crockett, second wife of Davy Crockett, who married him in Tennessee in 1815. She died Jan. 31, 1860. Because Crockett fought for Texas and died at the Alamo, his heirs were eligible for a land grant, but Mrs. Crockett did not claim her grant until 1853. By that time all choice land was claimed and she had to give a surveyor half of her land for locating a tract for her gravesite. The monument was erected at Acton Cemetery by Legislative appropriation in 1911.

The site is open to the public.

Fort Fred Steele was established on June 20, 1868 and occupied until August 7, 1886 by soldiers who were sent by the U.S. Government to guard against attack from Indians. The construction of the Transcontinental Union Pacific Railroad across southern Wyoming 1867–1869, in turn, brought the cattlemen, sheepherders, loggers, tie hacks, miners, and merchants who changed the wasteland into Wyoming Territory. Colonel Richard I. Dodge, who selected this site on the west bank of the North Platte River, named the fort for Major General Frederick Steele, 20th U.S. Infantry, a Civil War hero.

During its heyday in the 1880s, the mining town of Elkhorn swelled to a population of 2,500. The boom ended in 1890 with the drop in silver prices and residents moved to other areas. They left behind two impressive structures, Fraternity Hall and Gillian Hall, which have been preserved as outstanding examples of frontier architecture.
