Black Canyon of the Gunnison National Park Magnet - 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 magnet representing Black Canyon of the Gunnison National Park. Pick one up and add to your collection.
