At McCormick's Creek State Park in Indiana, this historic building was constructed in 1933 by the Civilian Conservation Corps and became part of the New Deal-era development that shaped the park’s visitor facilities. A one-story frame structure with board-and-batten siding, American Craftsman elements, a hip-roofed main block, and a gabled wing, it is especially noted for its large stone fireplace. In 1936, the Works Progress Administration rehabilitated it for use as a nature museum, a function it continued into the 1970s. Its architectural character and its ties to Depression-era public works led to its listing on the National Register of Historic Places in 1993.
