30 U.S.C. § 162 — Entry of saline lands; limitation

This section lets people claim public land valued for its salt. It covers all unoccupied public lands of the United States that contain salt springs, or deposits of salt in any form, as long as the land is chiefly valuable for that salt. This land is subject to location and purchase, under the provisions of the law relating to placer-mining claims (a type of mining claim for loose or scattered minerals). There's a limit: the same person cannot locate or enter more than one claim under this section.
