Golden Spike National Hist. Park Pin - Benchmark
Show your support for national parks on your sleeve, lapel, bag, or wherever! Our cast metal pin replicates the benchmark for site of the last spike at Golden Spike National Historical Park. 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. This one calls out the site at which the final spike was driven to connect America's first transcontinental railroad. A handy butterfly clutch attachment securely affixes the pin to any fabric surface.
- Official park pin approved by the National Park Service for Golden Spike National Historical Park
- Size: 1 1/8" round
