The mega 12-story-tall screen house at the Rogers City Quarry remains a landmark engineering feat amidst what is said to be one of the world's largest open-pit limestone quarries. The structural steel-and-brick-faced building shields a massive circuit from the region's often-blustery freezing climate. Monolithic in scope, a total of 64 screens process the material feed, sizing and separating from floor to floor. A variety of products are sent to stockpiles along the descent, with the finest material landing on the first floor as sand.
