South Dakota is best known for two things: cold winters and Mount Rushmore. Weil-McLain, the Michigan City, IN-based boiler manufacturer, is helping to keep visitors one of the country’s most recognizable national monuments warm.
Located in Keystone, South Dakota, Mount Rushmore depicts the faces of presidents George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. The faces on the mountain are 500 feet up, while the faces themselves are about 60 feet in length.
