In 1879, the U.S. Government gave 621 acres of land to the
Northern Pacific Railway, and part of this became
Ypsilanti Township and the townsite of Ypsilanti. The townsite of Ypsilanti was platted by William Hartley Colby and a partner by the name of Lloyd DePuy. W.H. Colby had come from
Ypsilanti, Michigan, so he named the new townsite after the
Michigan city by that name. The Ypsilanti Post Office was first established in the Theodore Doughty home, one-half mile north of Ypsilanti, which also served as the Ypsilanti
stage coach stop. In 1882, the post office was moved to Ypsilanti proper. At one point, date uncertain, the post office was moved to the Spaulding Store, where it remained until 1921, when it was moved to the Lee Ferguson Store. In June 1953, an addition was built onto the Heffernan house, which served as the post office until September 1, 1967, at which time a stand-alone post office was constructed. The dam at Ypsilanti Park was constructed in 1931 and 1932, as a
W.P.A. Project. Shortly afterward, the park was built alongside the dam. Ed Whitney donated the land where the park is located, while the original park equipment was contributed by Ypsilanti businesses and organizations, and James Crouch built the first two fireplaces at the park. The chief organizers of the park construction were Stan Nicholls, Bob Kotts, and a man named Glaspell. ==Climate==
