History.
Chase Grain Elevator was constructed in 1922 on the site of a previous Chase & Sons elevator that burned down in the winter of 1921–22. The fireproof tile elevator was planned to have a capacity of 13,500 bushels. In March 1922, it was expected to cost $20,000 ( today).
The elevator is said to illustrate experimental construction techniques during the transition from between wood and concrete elevators. Tile elevator construction ended around 1925.
The elevator consists of two cylindrical grain bins, with a third "pocket" bin created from a semi-circle of tile linking the two main bins.
