A nice way to get a two-fer. My "BM" series of caches will consist of hides very close to Benchmarks. Get a Cache and a Benchmark in one shot.
This hide is right on the Benchmark which is a "Stack" type of marker. To learn more about Benchmarking just click on the "Find A Benchmark" link on the left.
No need for an accurate waypoint for the benchmark as it's really the same coords as the cache. This will be one of the easiest Benchmarks that you'll ever find. To easily get to the page of this Benchmark just click on "...all nearby Benchmarks" in the "Find..." section below.
