In Moab, Utah there is a giant pile of RRM(Residual Radioactive Material) or Uranium Mill tailings from the Uranium mining done there in the 60s and 70s. It sits in a big pile next to the Colorado River. It is being picked up, put in containers, lidded, cleaned off, and put on a train to move it 30 miles away to be dumped and covered in a secure cell where it won't leech into the waterways. Each container, looks like this one below. This cake was made to celebrate the 2 Millionth ton of RRM relocated.
