Mount Rushmore National Memorial is located along the northeast edge of what is known as the Harney Peak Granite Batholith in the Black Hills of South Dakota. A batholith is a geologic feature that formed by the cooling of a large igneous body of magma below the earth's surface; if a similar igneous body reaches the earth's surface, it would form a volcanic feature such as a lava flow. The Black Hills magma was emplaced into the older "host" mica schist rocks during Precambrian time, approximately 1.7 billion years ago! Source: National Park Service

Well, Mount Rushmore is the mountain; that the landmark Borglum carved shares the name is perhaps shorthand. The Black Hills is the geologic range. It is located in the southwest corner of South Dakota, close to the town of Keystone, and is carved into the northwest face of Harney Peak.
Carving was done by using dynamite to blast away more than 90% of the rock. Once there was about 3 to 6 inches of rock left to remove, they used a technique called "honeycombing", drilling holes very close together, which weakened the granite so that it was easier to remove. After the honeycombing, the granite was smoothed with a hand facer or a bumper tool, creating a surface as smooth as sidewalk.
