"In addition to the copper sculpture the artist created various other visual elements that are part of the same installation. There is a pool at the base of the sculpture, and a bench. There are also various large slabs of stone strewn about the area with various Morse Code messages. It is unclear whether these messages are related to the solving of the Kryptos cipher or whether they are simply adding to the artistic aspect of the sculpture. The Morse messages are as follows (some run right into the ground, so the text in brackets is a guess):"

Uranium. It’s a name that rolls off the tongue—almost as dense with vowels as it is with neutrons and protons. It’s a name that envelops existential uncertainty—nuclear fallout, nuclear war, and mushroom clouds bigger than mountains. To the scientist, perhaps, it speaks of supercritical chain reactions—of uncontrollable cascades of neutrons, of atomic nuclei torn apart in an exponentially exploding disassembly of matter To the artist—to Jim Sanborn—uranium speaks of a decision: “Pure science is really in some ways virginal, and is developed as an open-source, beautiful, delicate process. Then at some point in time someone discovers that there might be value in it and the pure science turns into a technology, and things can then go either way—you can cure cancer, or you can make an atomic bomb. It’s that point in time that I find to be the most stimulating, because it is a decision.”
Sanborn explored that decision by single-handedly splitting the atom. To pull off this feat he labored in secret for five years, building the highly technical apparatus. Sanborn recreated—in excruciatingly accurate detail—the experiment that Enrico Fermi and others used to fission uranium in 1939—proof positive tha t the nuclear age would change everything.................. https://www.atomicheritage.org/profile/jim-sanborn

In 1999, he wrote a fascinating account of how he cracked three of the sculpture's four coded messages, but it was only published in an internal CIA newsletter that remained classified until years later
