Art Deco The Musée d'Art Moderne de la Ville de Paris, and the esplanade in front of the Palais de Chaillot, facing the Eiffel Tower, was crowded with new statuary by Charles Malfray, Henry Arnold, and many others. In the United States, many European sculptors trained at the École des Beaux Arts in Paris, came to work; they included Gutzon Borglum, sculptor of Mount Rushmore Lincoln Memorial. Other American sculptors, including Harriet Whitney Frishmuth, had studied with Auguste Rodin in Paris. The 1929 stock market crash largely destroyed the market for monumental sculpture, but one grand project remained; the new Rockefeller Center.
Needles (Black Hills) location was rejected by the sculptor Gutzon Borglum owing to the poor quality of the granite and the fact that they were too thin to support the sculptures. The Needles attract approximately 300,000 people annually. The area has a rich history of bold climbing by greatest climbers of their era, and has long been known for its purist ethics. In 1936 Fritz Wiessner climbed the "Totem Pole" and in 1937 "Khayyam Spire" with Bill House and Lawrence Coveney. In 1947 Jan and Herb Conn moved to the area and over the next couple decades put up over 220 first ascents.
