Knagur Green: Due to no response from the CO after the request to maintain or replace the cache, I am archiving it to, stop it showing on the listings and/or to create place for the geocaching community.

The Geocache Maintenance guideline explains a CO's responsibility towards checking and maintaining the cache when problems are reported. Caches that have been archived for lack of maintenance will not be unarchived. This is explained in the Help Center

Access times (updated August 2017):

  • May to August: 8:00-15:00
  • September to April: 06:00-15:00

UPDATE: I suggest attempting this cache during week-ends, when the gate is manned by an official of Tshwane Nature Conservation. During week days, it’s unlocked by a private resident who might not always be available.

Celestial Navigation is the art and science of navigating by the stars, sun, moon, and planets, and is one of the oldest of human arts. With the rise of radio and electronic means of finding location - especially with the increasingly popular GPS, based on satellite transmissions that can tell us our latitude and longitude within centimeters - knowledge of celestial navigation has experienced a precipitous decline.

The cache is not at the published coordinates, please solve the puzzle below for the final location.

Just about to take some readings with my “trusty” GPSr, its batteries died on me. Fortunately my theodolite was nearby and some of the brighter stars were becoming visible, so I took some measurements.

Using the observations and a decent star almanac, the stars were identified and the height and Azimuth was calculated for each, using the published coordinates for this cache as the assumed position.

Star No. Calculated Altitude Observed Altitude Calculated Azimuth
1 44°28’45” 44°28’47” 60°
2 38°47’34” 38°47’29” 307°
3 41°39’50” 41°39’54” 164°
4 42°14’32” 42°14’31” 228°


  • LOP
  • Use the observations as is, without applying any corrections.
  • Your answer will be a integer number of arc seconds from the published coordinates.
  • Assume that the Earth is a perfect sphere, and that the astronomical earth position will coincide exactly with the WGS84 position.
  • The difficulty level is based on the puzzle, finding the cache is easier.
  • Template.
  • GOAT
  • More information can be found on this website.

I could have put the final co-ords here, but I didn't.
