P...There is social history, and political history. Prior to 1860, mining claims were recorded at the local court house and it was the wild west. In 1872, this was codified in the general mining laws, and included "hard rock" minerals and carbon minerals. The abuses where significant, and carbon based "rock" (e.g. coal) was changed again by the Mineral Leasing Act of 1920, which is what we have today. Hard rock minerals again changed in 1976 (FLPMA), were the "claims" had to recorded at the Bureau of Land Management State offices. This rich history is explained in Gate's History of Public Land Law Development, which lead to FLPMA in 1976. You can go to the BLM's cadastral survey plats and Master Title Plats, and find the Historical Index (HI) which gives dates and authority for each of the claims, or other recorded lands actions on this map. If you give me the T and R for this township, I'll look it up. Quite often mining claims (before patenting) never made it to cadastral survey maps.
