America’s Building Stone
THREE HUNDRED MILLION YEARS IN THE MAKING
Over 300 million years ago, an inland sea covered most of the Midwest. During the recent ice age, gigantic glaciers slid south over Southwestern Indiana and exposed a small area of ancient bedrock between Bloomington and Bedford, Indiana. During the early nineteenth century, vast quantities of high-quality limestone were discovered and large-scale quarrying operations began in 1827.
Since large-scale quarrying operations began, Indiana limestone has been used in familiar American landmarks such as the National Cathedral, Pentagon, Rockefeller center and a host of other buildings, landmarks and monuments. Because of its strong, rugged, and solid characteristics, Indiana limestone has become known as “America’s Building Stone.”
