20. The Order: Washington First
As construction began, Washinton was the first to be carved into the historic mountain, beginning on July 4th, 1934. Jefferson followed in 1936, Lincoln in 1937, and finally Roosevelt in 1939. It took over 400 workers to complete the memorial and thankfully, there were no fatalities during the dangerous process. Surprisingly, the monument only took around $1 million dollars to make.
