Martin County’s industrial contributions are known nationwide. One of the county’s largest deposits of gypsum, an ingredient in drywall, is located in Martin County. As early as 1818, tool-sharpening whetstones were processed from the rocks around Hindostan Falls on the East Fork of White River.

Martin County’s icon uses cast acrylic gypsum and cast silicon bronze with chrome plating to represent vertically layered strata split by a glittering stream. The chrome-coated bronze used for the water reflects the blue sky as visitors pass by this piece.

Designers Jeff Laramore and David Jemerson Young of 2nd Globe, an Indianapolis–based artistic company, designed all 92 of the county sculptures featured on the outside of the Indiana State Museum. Their designs narrate the counties’ famous natives, historically significant events, or their cultural heritage, and were fabricated and installed by various Indiana sculptors, carvers, glassworkers, metal workers, and other artisans.
