The need to install an emergency generator at Jewel Cave National Monument in South Dakota will require a temporary halt in cave tours. Tours of the cave system will be unavailable from March 24 to March 28. On Tuesday, the visitor center wll be closed.
The monument plans to keep the visitor center open otherwise during this brief project on March 24 and March 26-28. The hours of the visitor center will be 8:30 a.m. to 4:30 p.m., with items from the Black Hills Parks and Forest Association available to purchase in the park store. Visitors to the monument will also be able to access and explore the Roof and Canyons Trails during this project. All tours are expected to resume on Saturday, March 29.
Any additional updates will be announced on social media and the park website’s social media pages.
Frank and Albert Michaud thought the formations they spied in 1900 through the cave's historic entrance might bring them riches, and filed the “Jewel Tunnel Lode” mining claim. While the calcite creations were not valuable in their own right, the brothers turned the cave into a tourist attraction. They were ahead of their time, though; tourism of the cave didn’t take off as they envisioned. In 1908 President Theodore Roosevelt designated it as a national monument, and soon thereafter the federal government bought out the brothers and placed Jewel Cave under control of the U.S. Forest Service, which turned it over to the National Park Service in 1933.
