Public Domain Lands
Federal lands that have never left federal ownership and are available for appropriation under public land laws, including the Mining Law of 1872.
Detailed Definition
Public domain lands are federal lands that have never left federal ownership through sale, grant, or other disposition. These lands are available for appropriation under the various public land laws, including the Mining Law of 1872 for locatable minerals.
Characteristics of public domain lands: - Owned by the United States since acquisition (by treaty, purchase, or cession) - Never conveyed to private parties, states, or other entities - Subject to the general public land laws - Managed primarily by the BLM
How public domain lands were acquired: - Louisiana Purchase (1803) - Treaty of Guadalupe Hidalgo (1848) - Mexican Cession - Oregon Compromise (1846) - Alaska Purchase (1867) - Gadsden Purchase (1853) - Cessions from original states
- Public domain lands: Original federal ownership, subject to general public land laws
- Acquired lands: Lands obtained by the federal government through purchase, condemnation, or donation from state or private owners
- Acquired lands are generally not subject to the Mining Law of 1872
- The distinction affects what laws apply to mineral development
Mining claims on public domain: Public domain lands that are unreserved and unappropriated (not withdrawn or set aside for a specific purpose) are generally open to the location of mining claims under the Mining Law of 1872.
