90% of the mountain was carved using dynamite. The powdermen would cut and set charges of dynamite of specific sizes to remove precise amounts of rock.
Dynamite was used until only three to six inches of rock was left to remove to get to the final carving surface. At this point, the drillers and assistant carvers would drill holes into the granite very close together. This was called honeycombing. The closely drilled holes would weaken the granite so it could be removed often by hand.
After the honeycombing, the workers smoothed the surface of the faces with a hand facer or bumper tool. In this final step, the bumper tool would even up the granite, creating a surface as smooth as a sidewalk.

∙ 11y agoDynamite and air hammers. An estimated 90% of the removed stone was loosened with dynamite. The fine sculpting was done with the air hammers. See link for more.
In addition:
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.

What is Mount Rushmore used for and why was it built?
Mount Rushmore is used to promote tourism in South Dakota. South Dakota State Historian Doane Robinson had the idea to carve the likenesses of western heroes in the Black Hills to promote tourism. His idea was to carve the Needles. Doane Robinson contacted Gutzon Borglum about a carving in the Black Hills. Gutzon Borglum chose Mount Rushmore instead because of the poor quality of granite in the Needles. Gutzon also thought it would be better for the sculpture to have a more national focus and chose the four presidents to carve on Mount Rushmore.
