This specimen is a cylindrical drill core recovered in 1891 during boring for iron in Michigan at a recorded depth of 590 feet and attributed to Merritt Stow. Core samples from this period document subsurface geology associated with early iron exploration and industrial development in the Great Lakes region. The piece represents both a geological sample and a historical artifact linked to 19th-century mining history, resource surveying, and the expansion of iron production in the United States. Its handwritten inscription preserves provenance, depth, and date, which are rarely retained on surviving cores of this age.
This item is suitable for collectors of industrial and mining history, Great Lakes regional history, geology and stratigraphy enthusiasts, natural history display, and museum or educational reference collections. It also appeals to those interested in early resource exploration, iron range development, and 19th-century industrial artifacts.
