Department of the Interior

The United States Department of the Interior was a pre-War department of the United States government. The Department of the Interior was a federal executive department responsible for the conservation of most federal lands, natural resources, and other related entities, such as the National Park Service and United States Geological Survey.
==Background==
One branch was the National Park Service, a division of the Interior Department responsible for the maintenance and protection of several public federal lands such as Acadia, Grand Canyon, Kanawha, and Zion National Parks. The department also oversaw the United States Geological Survey.
The department provided geological data and drew up plans for major construction projects. In the 1930s, the Bureau of Reclamation, a division responsible for water resource management, made the plans for the Hoover Dam. In the 2070s, they worked with the Vault-Tec Corporation, providing geological data for the company to construct their vaults.Vault 76 construction plansVault 79 construction plansVault 114 blueprints They also made the plans for the Congressional Bunker beneath the Whitespring Resort.Congressional Bunker plans In Appalachia, both the Department of the Interior and the Department of Agriculture held lands under their jurisdiction.Kanawha National Park and Monongahela National Forest

==Behind the scenes==
The Department of the Interior would have been mentioned in the canceled Fallout 3 project Van Buren.No Mutants Allowed posts on Van Buren: "Grand Canyon: Due to uranium demand shortly before The War, the U.S. government removed the GC's status as a national park and allowed private mining companies to exploit the GC's supply of uranium (yes, there really is uranium in the GC). The resulting mess was an environmental disaster. As a result, the Canyon has become one of the deadliest places in the wasteland, home to hideous mutant things seen nowhere else. Sane people avoid it; too bad The Prisoner will probably find himself in the deepest, darkest depths of the Canyon at some point..."
