DiveCaching | Geocaching


"Go somewhere, do something."


That is the basic idea behind Geocaching Challenges. Here at Mermet Springs, you will be challenged to scuba dive and hunt for the caches by navigating above and below the cool waters of the quarry.


What is geocaching? Geocaching is a real-world, outdoor treasure hunting game using GPS-enabled Dive Computers. Participants navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location. Geocaches can be found all over the world. At Mermet Springs, we have two caches for geocahers to find; one above the water and one below.


"Frozen Flight Scuba" Cache (geocaching tracking number GC2BM6X) Published in July 2010.

  • The cache is located in 60' of water so scuba diving skills are essential. You must be a certified scuba diver to access this cache. There is a $25 fee to dive in the quarry. Note the cache is NOT available 24 X 7. The quarry is open most days from 10AM to 6PM and closed on Wednesdays.

  • The cache is located in the cockpit of a Cessna plane sunk in the quarry.  To access the cache enter the water from the old primary dock. From the old primary dock surface swim SW to the 65' platform buoy (about 40'). Perform a controlled descent following the line to the 65' platform. From the 65' platform follow the yellow rope NW to the Cessna, passing the sunken pickup truck. The Cessna consists of the body only and does not have wings, engine, doors or glass.

  • The cache is located under the dash on the pilots side of the plane. The cache is a clear Plexiglas box that is slightly negatively buoyant. The cache is attached to the dash of plane via cable so it won't float away. The cache contains a waterproof log book and pencil. 


"Rock Quarry" Cache (Geocaching tracking number GC28AFN) Published in May 2010.

  • The cache is a full size ammo box located at a rock quarry. There is a small bluff located directly across from the cache that offers a great view of the quarry and is an excellent spot for photos. The cache contains a small camera. Pictures will be posted here (coming soon). Please leave the camera in the cache for others to use. Cache was placed with permission of the quarry owner, Glen Faith.

  • Note the cache is NOT available 24 X 7. The quarry is open most days from 10 AM to 6 PM and closed on Wednesdays. If the gate is locked DO NOT attempt to access the cache. Before searching for the cache PLEASE check-in at the office on-grounds. There is no fee to park or seek the cache provided you park at the coordinates listed. Cache is a short walk about 300 yards from the parking area. The quarry has several interesting objects sunk below the surface including a fire truck, semi truck, school bus and the Boeing 727 airplane used in the movie "U.S. Marshals."
