Benchmark Hunting Tool

A lot of geocachers also enjoy trying to locate benchmarks, in addition to "regular" geocaching. Like geocaches, there are probably several benchmarks, or survey markers, near you. You can search the National Geodetic Survey database for local benchmarks here.

I recently came across this nice little survey marker searching tool that uses the Google Earth plug-in to map benchmarks for any given query. First, center the map in your desired location. Then, Under the NGS Control Station heading, select the "Query Setup" radio button. Filter your search if you like in the dialog box that pops up, and/or just click "OK". The search will return a display of all the different types of control points within a fixed radius of your search location. A useful tool to add to your geocaching/benchmarking arsenal.

Cache On!
