This whereigo cache covers five benchmarks and then will lead you to a final physical geocache. All of the benchmarks are easy to discover and there is parking nearby. The final is a physical geocache container with a log to sign.
Note: You must go to each location to unlock the coordinates to the final physical cache.
In surveying, benchmark is a survey marker with a precisely known vertical elevation. The term benchmark originates from the chiseled horizontal marks that surveyors made in stone structures, into which an angle-iron could be placed to form a "bench" for a leveling rod, thus ensuring that a leveling rod could be accurately repositioned in the same place in future. These marks were usually indicated with a chiseled arrow below the horizontal line. More enduring benchmarks may be chiseled into a wall (the usual type in the UK) or marked by a small brass or aluminum, steel pin, or bolt attached to a stable foundation, such as a concrete post, bridge abutment, building, or a purpose-made concrete block. These markers are then used as starting points for subsequent surveys to establish the elevation of nearby points. The height of a benchmark is calculated relative to the heights of nearby benchmarks in a network extending from a fundamental benchmark, a point with a precisely known relationship to the level datum of the area, typically mean sea level.
What is a Wherigo Geocache?
Wherigo is a new way of utilizing GPS technology to play games, take tours, and yes geocache. Visit Wherigo.com to learn more about this new software.
Do I need special equipment?
Yes! To find this cache the proper way and to truly experience the hunt the way it was meant to be experienced, you will need two things, both of which you can get from Wherigo.com
1. The Wherigo Player.
Note that the Wherigo Player comes pre installed on the Garmin Colorado & Oregon series GPSr units. A version of the player is available for download for use by GPS enabled Pocket PC devices and smartphones on Wherigo.com.
2. The "Benchmark Hunter" cartridge.
This is also available at Wherigo.com.
