Half-Life of Memory

Half-Life of Memory is an exhibit that examines the legacy of the Rocky Flats Nuclear Weapons Plant. Through a range of media, the exhibit brings together personal testimony, historical evidence, and artistic interpretation to explore how this history continues to reverberate through the land, nearby communities, and the nation’s nuclear arsenal.

The show’s artist and filmmaker, Jeff Gipe, grew up in Arvada and attended Arvada West High School in Jefferson County. His father worked at the Rocky Flats plant, but like many who came of age nearby, he was largely unaware of the site’s realities. That personal connection became the foundation for a body of work exploring the history and human impact of Rocky Flats.

Drawing on more than a decade of research, interviews, artworks, and archival materials, the exhibit presents Rocky Flats not as a closed chapter of the Cold War, but as a living history with ongoing consequences. As the United States enters a renewed era of nuclear weapons production, Half-Life of Memory reflects on an unresolved nuclear legacy that will endure beyond plutonium’s 24,000-year half-life.

"PLUTONIUM HAS A HALF-LIFE OF 24,000 YEARS. THE HALF-LIFE OF MEMORY, BY CONTRAST, IS A MUCH BRIEFER THING... THE CONTAMINATION AT ROCKY FLATS WILL LONG OUTLIVE OUR EFFORTS TO CONTROL OR EVEN REMEMBER IT."
