Byal Orchard Historic District is a nationally recognized historic district located northeast of Mingo, Iowa, United States. It was listed on the National Register of Historic Places in 1994. At the time of its nomination it contained three resources, which included two contributing sites, and one contributing structure. It includes four strands of top-worked apple trees that were planted 1933 to 1934, and a windbreak of Ash and Mulberry trees that were planted in 1936. They both count as the sites, and the structure is a network of traffic corridors that were established 1933 to 1934. Its historic significance comes from the symbiotic relationship between science and practice in Iowa agriculture. They used planting techniques that were advocated by researchers at Iowa State College, now Iowa State University, and carried out by progressive fruit growers like Hugh and Roscoe Byale. In this instance they employed Hibernal root stock and top-work grafting. The Armistice Day Blizzard in 1940 wiped out most of Iowa's apple orchards, but it validated the techniques employed here.

The Calamus Creek Bridge near Maxwell, Iowa is a concrete Luten arch bridge constructed in 1905. It was built by N. M. Stark and Company for a cost of $900. It has a 25-foot (7.6 m) single span and a total length of 45 feet (14 m).In 1998 the Calamus Creek Bridge was listed on the National Register of Historic Places (NRHP), on of several N. M. Stark Luten bridges on the register.The NRHP nomination for the bridge says: Before the codification of bridge design in the state in 1913, Stark built perhaps hundreds of Luten arches throughout Iowa, in exclusive contracts with Story and other counties. This structure in Story County is distinguished as the earliest remaining Luten arch in the state. In fact, with its 1905 construction date, it is one of the oldest Luten arches in the country, built in the same year as Daniel Luten received his patent. For this reason, it is a technologically significant, transportation-related resource.: 5
