The problems faced due to a shortage of funds put a halt on the monuments original plans. But then the United States government authorized Gutzon Borglum’s special addition. So within the years 1938 and 1939, a 70-foot tunnel behind Abraham Lincoln’s head had been carved on the mountain. This, according to the great sculptor Borglum, would serve as the entrance of what would be referred to as “The Hall of Records at Mount Rushmore.” The initial plan for the idea of the Hall of Records was for it to serve as a time capsule. Gutzon Borglum’s plan was to let the future generations walk through the entrance and get to learn more and experience the history of the United States and all that it has achieved. But sadly, Borglum passed in the year 1941 before the entire monument could be finished. His son Lincoln began taking his role to oversee the remaining work that needed to be done to complete the site.
