How Geocaching Works

Please note Use of services is subject to the terms and conditions in our disclaimer.

Geocache Description:

Flash forward to 30th century Earth, a planet defiled with slag, ash and clinker. Once again, brutal and callous crimes compel the Doctor and his allies to fight the malevolent forces which threaten the human race. But which marauding menaces is it this time?

Anyway, enough blether of these intergalactic shenanigans. Distort these numbers with your Dynatrope to locate the true position of the cache. Once you’ve sorted the numbers out, jump in the Tardis (or the Whomobile, of course), don your Biodamper and celery, fill your pockets with Jelly Babies and come and get it!

And don’t worry, excessive radiation doesn’t affect these parts for another eight and a half centuries.

At GZ, the following items from your Tardis Tool Kit might come in handy:

  • Portable Scanner – in Chronometer mode to ensure you know the correct time and date in your current location with planetary rotations and solar cycles factored in. Of course, it will also detect other time ships in the area.
  • Stalos Gyro to suspend radioactive half-life levels. Just in case any radioactivity has seeped in from the future.
  • Master Drone Clamp – in case of GPSr malfunction or battery failure.

You might also need some of the more advanced features of The Sonic Screwdriver:

  • Sonic-Electro Impulse Generator mode – to neutralise the laser trip wire around the cache. Remember to reverse the polarity, or you could be in trouble. (Alternatively, you could use it to detect threats to your head and eyes).
  • General Harmonic Frequency Audio Producer mode – to hypnotise any inquisitive muggles near GZ. (Alternatively, you could employ your best caching stealth moves).
  • Kinetic Impulse Generator mode – to unlock the cache container. (Alternatively, you might find that your hands do just as well).

When placed the cache contained a few bits of cosmic jetsam and flotsam, including an alien from Torajii Alpha, a number randomiser from the 26th century, a rock from Miasimia Goria, a carabiner from Raxacoricofallapatorius and a ocular perception filter, as well as The Sonic Screwdriver Travel Bug, which fittingly started its travels here.

Just in case the Tardis is temporarily out of action and you are not able to jump forward in time to see the yellow smiley face of success, you can check your numbers here.

IMPORTANT INFORMATION: When setting the chronometer, ensure you program it for between the hours of 10am and 5pm GMT (or BST) Earth Time, also ensure you visit between a Wednesday and Sunday during term time. GZ is open every day during school holidays (as they stand in the year 2011), except Christmas Day and New Year's Day. There is a sonic force field that even The Screwdriver can't crack at all other times. Many thanks to SkiCycle for the info (and apologies for the wasted visit Particularly embarassing as the cache started life with a 24/7 attribute... ). 

Have fun and stay safe...

This is one of a series of caches based on locations used for filming Doctor Who. If you want to add to the series, just let Pezzini know so she can keep track of the numbers without duplicates. Please keep to the naming convention of starting cache titles in the series with "Who Was Here: "
