Boulder County, Colorado Surveys and Mineral Claims at the General Land Office, 1859-1876: An Annotated Index

The Boulder County, Colorado Surveys and Mineral Claims at the General Land Office, 1859-1876: An Annotated Index contains the names of the mine owners (claimant), surveyors and survey crew members, along with the mines and their range and township information. One additional piece of information was added when found—cabins, houses, barns, buildings, bridges, boarding houses, mills, toll roads, wagon roads, creeks and rivers. Using those listings is one way to see what was built where during these early mining days.
