Officials at Mount Rushmore National Memorial will install a temporary highline Sunday in preparation for next week's Independence Day celebration.
According to a news release from the National Park Service, the memorial's technical ropes access team will begin installing the highline system that will ferry supplies to the top of the memorial for the massive fireworks display on July 3.
The highline system consists of a 1350-foot highline rope and trolley pulley system. It will be temporarily connected to the Presidential Trail at the base of the memorial and reach the top of the mountain where a tripod will be installed on the top of Theodore Roosevelt's head.
Firework loads and equipment will be secured to the pulley and pulled to the top of the sculpture using an electrical winch.
Parts of the Presidential Trail may be temporarily closed while loads are lifted up the mountain, NPS officials said.
In addition to hauling the fireworks to the top of the Memorial, the highline system is used in preservation efforts, including checking rock monitoring systems and crack sealant. It is also used by the ropes team as a rescue device for medical incidents on the mountain.
The system is being set up in the same location where a tramway existed in the 1930s during construction of the sculpture, according to the release. It will remain in place through Tuesday.
The highline will be reinstalled on July 5 to remove firework material from the top of the memorial on July 6 and 7.
