Benchmark Keychains

Keychains based on the surveying benchmarks used by various government agencies, including the United States Coast & Geodetic Survey (USC&GS), the United States Geological Survey (USGS) and the United States Lake Survey (USLS).

Use the maps at the following link to discover the surveying benchmarks in your neighborhood or favorite locations: Benchmark Maps. If you find a benchmark you are interested in, let me know and I can see if I can make a replica for you. Also, I can customize any of the replicas already in my shop with custom text engraving. Just let me know what you are looking for using the "Send Message" button below!
