This series of caches was inspired by the excellent Indiana Benchmarking series. I am adding to the Ohio series started by Folboter JAF. The caches highlight benchmarks in Ohio. Each cache will bring you close to a loggable benchmark or in this case 4 loggable benchmarks... so this find can be a five-fer!
You may find a bookmark list of the Ohio series at Ohio Benchmark-Friendly Geocaches.
The cache is a simple micro on a guard rail and two of the benchmarks are disks set in concrete and two are pins in pipes that is marked by a waypoints on this cache page.
The benchmark can be logged using:
