Sculpture of the United States are at least three major mountain sculptures in the United States. These are Mount Rushmore, Stone Mountain, and Crazy Horse Memorial. Gutzon Borglum, an accomplished sculptor with such pieces as "Seated Lincoln" and a variety of other public monuments, oversaw the sculpture of Mount Rushmore in the Black Hills in South Dakota. The monument was finished after his death by his son Lincoln Borglum. Gutzon Borglum also was responsible for starting the Stone Mountain project in Georgia but had a falling-out with its overseers. The monument was then taken up by Augustus Lukeman, who died during its carving in 1935.
Cornelia Van Auken Chapin had formerly belonged the Gutzon Borglum, with Marion Sanford. In the summer of 1949 she was one of 250 sculptors who exhibited in the 3rd Sculpture International held at the Philadelphia Museum of Art. From 1951 to 1953 Chapin served on the New York City Art Commission. Chapin was most famous for her sculptures of birds and animals, though she also sculpted human figures. Between 1930 and the early 1960s, Chapin exhibited in galleries in New York, Connecticut, Pennsylvania, California, Washington, DC, New Jersey, Maine, and Paris, and won numerous awards and prizes for her work during the 1930s and
