The Bureau of Exploration was founded in 1902 as a secret sub-department of the United States Bureau of Reclamation. Its mission was simple: to discover and catalogue bizarre, lost, and beautiful locations. For over a century, Bureau operatives have ventured across the country, seeking out and recording majestic abandoned structures, clandestine natural wonders, and the otherworldly aspects of the everyday.

Initially this was for land development purposes, yet in recent years the Bureau of Exploration has dedicated itself instead to spreading knowledge of these extraordinary locations to the public. Here we provide records of our expeditions to fantastical and forgotten places.
