The atomic cloud logo of the Richland High School Bombers, which reflects the pride in the Richland area for the community's role in the development of the Manhattan Project and the end of WW II, is seen on the floor of the high school's gymnasium in Richland, Washington, USA, 28 May 2015. Richland is home to many workers from the nearby Hanford Site, which was established near the end of WW II to make plutonium for nuclear weapons. Hanford plutonium was in the so-called 'Fat Man' atom bomb that the US dropped on Nagasaki in 1945.
