Extreme Benchmark Hunting
Extreme Challenges

Some Geocachers have managed to find stations that have been previously reported NOT FOUND by multiple organizations. Searching for stations that have eluded previous recovery efforts is a special kind of challenge, but a successful recovery of such a station will bring wealth, fame, and glory to the seeker. Well, maybe not, but it will bring a deep inner satisfaction.

Triple Challenges

These extremely challenging stations have been reported NOT FOUND by three well-known organizations:
  • USGS - The US Geological Survey
  • CGS/NGS - The US Coast & Geodetic Survey / National Geodetic Survey
  • USPSQD - The US Power Squadrons

There are 737 such stations out of the approximately 760,000 stations nationwide. This list of stations is available here in the form of a .ZIP file containing an Excel spreadsheet. An online inquiry may be developed in the future.

Double Challenges

These challenging stations have been reported NOT FOUND by two federal organizations:
  • USGS - The US Geological Survey
  • CGS/NGS - The US Coast & Geodetic Survey / National Geodetic Survey

There are many such stations, so to reduce the size of the list, only those stations that were last reported NOT FOUND were included.

There are 4,225 such stations out of the approximately 760,000 stations nationwide. This list of stations is available here in the form of a .ZIP file containing an Excel spreadsheet.
