The Rushmore Memorial Library, also known as the Rushmore Memorial Building, is located at the junction of NY 32 and Weygant Hill Road in Highland Mills, New York, United States.
It is a small Arts and Crafts-style stone building constructed in the 1920s with a donation from Charles E. Rushmore, a local resident for whom Mount Rushmore is also named.
It served as the Town of Woodbury public library until the mid-1980s, when a larger modern library was built.
Today it is the headquarters of the town historical society.
It was listed on the National Register of Historic Places in 2008, after two previous efforts in the 1980s failed. 
 Mount Rushmore Needles  
Charles E. Rushmore (December 2, 1857 – October 31, 1931) was an American businessman and attorney for whom Mount Rushmore is named.
Born in New York City, he was the son of Edward Carmen Rushmore and Mary Eliza (née Dunn) Rushmore, of Tuxedo Park, NY.
He was married to the former Jeanette E. Carpenter.
In 1883, a tin mine, the Etta, was opened, which caused excitement among Eastern investors.
In 1885 Rushmore was in the Black Hills of South Dakota to check the titles to properties for an eastern mining company owned by James Wilson.
Although an Easterner, Rushmore quickly made friends among the miners and prospectors.
One day he was returning to headquarters of the Harney Peak Consolidated Tin Co., Ltd., located at Pine Camp, which was north of the great granite peak soon to bear his name.
With him were a local business man, and William W. Challis, a prospector and guide.
As they neared the mountain, Rushmore turned to Challis and asked its name.
Challis jestingly replied: "Never had any but it has now - we'll call the thing Rushmore."
According to rancher Jerry Urbanek, Rushmore returned to the Black Hills annually to hunt big game.
One day, while accompanied by Ted Brockett of Keystone, South Dakota, Rushmore asked the name of the mountain and was told that it was Slaughterhouse Rock.
Rushmore joked that his annual treks to the Hills had earned him the right to have the mountain named after himself.
"So just for the hell of it," Urbanek claimed, the locals started calling the hill Mount Rushmore.
Whatever the precise story, the United States Board of Geographic Names officially recognized the name "Mount Rushmore" in June 1930."
Forty years after the initial 1885 naming, Rushmore donated $5000 towards Gutzon Borglum's sculpture of the four presidents' heads on the mountain - the largest single contribution.
The Memorial was dedicated by President Coolidge on August 10, 1927.
Rushmore was also a member of the Phi Gamma Delta Fraternity. 
Because of its fame as a monument, Mount Rushmore is frequently discussed or depicted in media, film and popular culture.
The memorial was iconically used as the location of the climactic chase scene in Alfred Hitchcock's 1959 movie "North by Northwest".
Scriptwriter Ernest Lehman recalled that in the course of screenwriting, Hitchcock "murmured wistfully, 'I always wanted to do a chase across the faces of Mount Rushmore.'"
The scene was not actually filmed at the monument, since permission to shoot an attempted killing on the face of a national monument was refused by the National Park Service.
In the movie, the villain's house is located on a fictitious forested plateau behind the monument. 
Bismuth is located in the Black Hills on the northern border of Custer County, South Dakota, United States.
It was built just north of Iron Creek and is about 1.5 miles northwest of the ghost town Spokane, South Dakota, and 5 miles southeast of Mount Rushmore.
