Great Sand Dunes National Park Magnet - Benchmark

While X marks the spot where treasure can be found, these metal disks - known as benchmarks - mark a geological treasure! Benchmarks show land surveyors, engineers, map makers, and other professionals their exact position on the earth. Not only do they serve this surveying purpose, but they are also seen as treasure for some location hunters. People across the US search out these bench marks to see how many they can find. The unique importance of these metal discs is why we've produced a cast metal benchmark magnet representing Great Sand Dunes National Park and Preserve.
