A specialized version of the munitions bunker called a Gravel Gertie is designed to contain radioactive debris from an explosive accident while assembling or disassembling nuclear warheads.
It was named after the character of the same name from the Dick Tracy comics; the compressed mass of gravel forming the ceiling of the bunker reportedly reminded researchers of Gertie's grey, curly hair.
