Department of the Interior

The Department of the Interior was a pre-War department of the United States government.

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.

In the 2070s, they worked with the Vault-Tec Corporation, providing geological data for the company to construct their vaults. They also made the plans for the Congressional Bunker beneath the Whitespring Resort. In Appalachia, both the Department of the Interior and the Department of Agriculture held lands under their jurisdiction.

During the Great War, the Secretary of the Interior took refuge in the Whitespring bunker alongside the Secretary of the Treasury and Secretary of Agriculture Thomas Eckhart, though died shortly after arrival.
