The Bureau of Standards was consulted on the design of the Crypt and advised how artifacts should be stored. The chamber resembles a room of an ancient Egyptian pyramid with artifacts placed on shelves and the floor. Many items are stored in stainless steel holders, lined with glass and filled with an inert gas to prevent aging, a concept later carried over to the Westinghouse Time Capsules. The walls are painted with pictographs by George L. Carlson that show the history of intelligence and human development. There is a small windmill inside the vault that will make electricity to operate the electrical items buried in the time capsule.
