Introduction: The United States Public Land Survey (USPLS) started with the Land Ordinance of 1785 and covers all US land that was not settled by the time of the official government survey. It does not include the east coast states including Kentucky and Tennessee or Texas. Small areas of other states that were settled before the survey also technically excluded. This explains the odd shapes of many mining claims in the west. Latter title transfers followed USPLS lines.
