The Emerson Parks House is a locally unusual example of a two-story log residence in Ten Sleep. It stands as one of the few remaining houses that represents the early history of the Ten Sleep community. It was built in 1929 for Emerson Parks and his wife Ina Miller Parks at a time before Ten Sleep became a town. Parks was a well-educated man and was a noted geologist and cartographer who had noted interests and knowledge of the underground movements of water as well as the practical uses of bentonite.

Previously known as the Ten Sleep Mercantile, this two story commercial structure embodies the vernacular architecture of the frontier era and has acted as a community focal point since the turn of the century. The Ten Sleep Mercantile is representative of the detached retail store featuring tall, narrow and deep interior shop space that can be found throughout rural American towns and is a style of architecture particularly associated with frontier communities. As a significant component of community life, such structures generally served dispersed rural populations. In many instances communities derived what little identity they had from stores that served not only as the community supplier but social center. H. T. Church created the Ten Sleep Mercantile in 1902. The expansion of business led to the construction of the permanent Ten Sleep Mercantile building in 1905 which quickly emerged as one of the town's principal focal points. Local merchant and historian Paul Frison operated the Ten Sleep Mercantile between 1919-1943. Frison was a prominent figure in county politics serving as a justice of the peace, mayor of Ten Sleep, and state legislator. An avid avocational historian, Frison detailed the area's history and folklore in five published books and in assorted manuscripts and texts.

Constructed in 1917 for C. C. Worland, a local prominent businessman, the Worland House is an outstanding example of the bungalow style which made a significant impact on building traditions throughout the United States. The style, which suited the Wyoming environment and was easily adapted to accept ''Prairie and Craftsman'' influence, quickly became popular with both the upper and middle class. Charlie Worland, son of the town's founder was a leading businessman who demonstrated a sharp talent for accumulating wealth. Worland ran a multifaceted business operation from his home in Worland which included interests in oil, gas, minerals, farming and ranching, and influenced the broad patterns of the community's commercial development. Charlie and Sadie Worland moved into their new home in 1918. While they lived there they entertained a great deal. The basement contained a huge open room in which dances were held. These dances were attended by many young people of the town. In 1925, the house was sold to the president of the Stockgrowers State Bank, G. C. Muirhead. His family lived there for 53 years, until 1978.
