Show your support for national parks on your sleeve, lapel, bag, or wherever! Our cast metal pin replicates the benchmark placed inside the "Big Room" at Carlsbad Caverns National Park by the US Geological Survey in 1934. A benchmark is a permanent mark established at a known elevation and used as the basis for measuring the elevation of other topographical points within a given area. A rubber stud clutch attachment securely affixes the pin to any fabric surface.
