How Geocaching Works

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

Geocache Description:

The cache IS at the posted coordinates, but you MUST fulfill the requirements below in order to log a find on this cache!

Logs that have not met the challenge requirements WILL be deleted.

The 2.5* difficulty rating relates to finding the container, rather than the difficulty of completing the challenge

The approach path to the cache has some yellow hazard tape strung across it. This is a temporary measure due to nearby tree felling and clearance work, and you are free to go round the tape providing that no machinery is in use

Chemistry can be fun, especially when it involves geocaching.

There are currently 118 different elements, each with a unique symbol. If you choose to do this challenge you must find and log 100 caches with 100 different chemical element symbols in the GC code. Each element can be counted only once towards the 100 total.

Simple rules:

1. Since several letters are not used in GC codes, here are the substitutes:

  • Number 0 (zero) for the letter O.
  • Number 1 may be used in place of I.
  • Use 5 to replace S.
  • V may be used for both V and U.
  • Use 7 in place of L. (so yes, Lu will be 7V).
2. All cache types, past and present, can be used for this challenge.

3. All of your cache finds can be counted, including those found before the publication date of this cache

4. Each cache can only be used for one element. If the GC is GC34BEB, you will have to choose which element to use, beryllium or boron. GC2MKPV can be used for potassium or phosphorus or vanadium, but only one of these.

5. The element symbol letters must be next to each other, and not separated by a number or letter. For example, if you are going to use Sn (tin), it must be like GC2V35N not GC1M50N.

6. To document your finds to log the cache, there are two choices. Once you have found your 100 caches create a bookmark and in the notes, list the element symbol you are claiming along with the GC code and Date Found. For example, GC1RBAD - Rb - Rubidium - 01/01/11. You may also make a list and post it to the cache page For the lists, include GC#, Cache Name, Element Name and Symbol and Date Found. Example: GC1RBAD - Death Valley - Rb - Rubidium - 01/01/11

7. You can sign the log for this challenge at any time and log a 'note' to the cache page, mentioning you signed the log. But you may not log a find until you have completed the requirements (this way you don't have to go back to sign after you complete the requirements!). Once you complete the requirements, edit your log, change it to "Found", and change the find date to the date you completed the requirements and list the required information.

Remember that Caching should be Fun
