Great Sand Dunes National Park Pin - Benchmark

Show your support for national parks on your sleeve, lapel, bag, or wherever! Our cast metal pin replicates the benchmark for the visitor center at Great Sand Dunes National Park & Preserve. 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.
