Red Mountain (Birmingham): Fossil Hunting in Jefferson County, Alabama

Updated July 2026

Red Mountain is the type area for the Silurian oolitic hematite that Alabama named its state mineral in 1967, the red iron ore that built Birmingham's steel industry. The Big Seam ore is a fossiliferous hematite packed with crinoid and brachiopod fragments, so specimens preserve both the state mineral and the marine life that formed it. Red Mountain Park protects the historic mines with free public trails, while loose hematite is best gathered from nearby road cuts and permitted dump ground rather than inside the preserve. Reported finds include hematite, fossils, chert. Below: coordinates, access notes, nearby spots, and trip-planning links.
