It consists of a reinforced concrete mill building with a long two-story wing and a more compact six-story section, adjoined by a reinforced concrete grain elevator with seven pairs of grain tanks.

The elevator features a large logo with a cowboy on a bucking horse and the legend "Best Out West Enriched Flour, Tomahawk Feeds For Livestock and Poultry, Sheridan Flouring Mills, Inc."[3] The elevator building is 144 feet (44 m) high, while the grain tanks are 110 feet (34 m) high.

As part of the hotel renovation, the interior partitions were removed from the mill building and new windows were installed, partially closing the openings with masonry.

The mill's products included wheat cereal and biscuit, doughnut, waffle and pancake flour, marketed as "Best Out West."

[4] The mill had a rail connection via a spur line of the Chicago, Burlington and Quincy Railroad.
