What stands out about Richfield Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Richfield was platted in 1885 and was named for the fertility of the land. A town was built up quickly: in less than one year, Richfield had 600 inhabitants. In 1886, Morton County was founded and Richfield was established as the county seat.
In the 1930s, the area was further affected by its location within the Dust Bowl. This catastrophe intensified the economic impact of the Great Depression in the region.
In 1961, the county seat was moved from Richfield to Elkhart. Richfield has subsequently been the center for basic services for residents of the surrounding rural region: school, postal, fire and police, food and fuel.
