Great Sand Dunes National Park Keychain - Benchmark

The benchmark is a permanent mark established at a known elevation that is used as the basis for measuring the elevation of other topographical points in a given area. Not only do they serve this surveying purpose, they happen to look cool too! That’s why we’ve produced a cast metal benchmark keychain representing Great Sand Dunes National Park. Pick one up and unlock your memories of this magical place.
