Here is the online version of a story I authored which will be in the next issue of The American Surveyor. Kurt Luebke and I have met several times in the Black Hills to search for USGS monuments using 114-year-old descriptions. It is an 8-hour drive for me and a 10-hour drive for Kurt, but it's the way we like to spend our vacations. We first connected with each other through the old POB message board. One small typo on the cover text should read "USGS Control in the 1890s" instead of the 1880s.
