(Statutes at Large\, Treaties\, and Proclamations\, of the United States of America\, vol. XVII\, chap. 152). This act outlined the method by which mining claims could be patented\, the first step being the discovery of a potentially productive site and recording of a claim or notice of location. Each notice of location recorded in these books indicates the name or names of locators\, provides a legal description of the location\, names the claim\, and usually the mining district\, and is signed by the county recorder. Recorded claims document three distinct periods of mining activity in Washington County.
