New Sealant And Constant Monitoring


So as to keep the structure intact and in good condition, the National Parks staff started removing all the old sealant and started replacing them with modern silicone. This would help the monument in handling a wide range of temperatures that the Black Hills are often faced with along with heavy rain. For the silicone to remain hidden, it was again dusted with granite powder. With the new silicone, an electric monitoring system was installed. This enabled the caretakers to be alerted with even a slight movement, ones as minute as 0.0001 inches. The temperature of the granite can also be recorded with this new installation. This could definitely prevent further damages that the monument might face in the years to come.
