The park is open only during daylight hours.
A two stage multi cache. Both stages are an easy walk from the
parking areas. This cache is being placed in time for my GPS
Accuracy and Benchmarking event. The first stage has something to
do with a benchmark. BYOP.
The waypoint for the first stage is more accurate then any
waypoint that any regular geocacher could take. It was created by a
surveyor using a high end GPS. They took readings for the National
Geodetic Survey (NGS). So if your GPS doesn't read zero, then your
GPS is off. The final is a different story. I used three GPS units
to mark it for eight to nine minutes. I used a GPSMap 60C,a
GPSMap60Cx and an eTrex Vista. I averaged those three waypoints for
the final.
