Lake Mead National Rec. Area Magnet - Hoover Dam 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 detailing the benchmark for the famed Hoover Dam, the public work that created Lake Mead, and hence the Lake Mead National Recreation Area. Pick one up and add to your collection.

• Official park magnet approved by the National Park Service for Lake Mead National Recreation Area
