Between 1997 and 2002, archaeologists studied the living conditions of miners in southern Colorado by excavating the Berwind coal camp and the Ludlow tent colony, two sites from the 1913-1914 Colorado coalfield strike. Many of the strikers at Ludlow had come from the nearby company-owned town of Berwind. The work sought to determine the colony’s size and layout and to learn what remained underground. Archaeologists located individual tents and cellars by mapping surface artifacts and using traditional excavations, ground penetrating radar, and historic photo overlay, a method that projects a historic image onto a modern landscape. Historic photo overlay successfully located the remains of three tents in the colony’s northwest section about 100 feet ahead. Ground penetrating radar, which sends a radar signal into the ground to suggest what lies beneath without digging, located 8 buried cellars, two of which were fully excavated. Laboratory work cleaning, identifying, and analyzing artifacts was also vital, and by combining artifacts with their locations, archaeologists drew conclusions about daily life there.
