The first Boy Scouts of America National Jamboree was scheduled to be held in Washington, D.C., in 1935 to celebrate the 25th anniversary of Scouting in America. Unfortunately, the Jamboree was canceled because of a polio outbreak in Washington. When the first Jamboree was finally held in 1937, Dan Beard lit the opening campfire using flint and steel. Scouts from all 48 states brought the wood that was used in the campfire. There were 27,232 Scouts camped on the National Mall under the Washington Monument. Since that time, an additional 18 national Jamborees have been held, the last in 2017.
