Redgranite Outcrop Wisconsin State Rock
Red granite became the state rock in 1971. Granite is an igneous rock made up of a variety of minerals -- typically quartz, feldspar, mica, and hornblende. Granite is commonly used as a building and decorative stone. The Kenosha Gem and Mineral Society proposed red granite as a state symbol to help promote awareness of Wisconsin's geology. It was selected because of its abundance, uniqueness, economic value, historical significance, and because it is native to our state.
