Geocache Description:

20/11/2017 Update: I will be maintaining The Periodic Table series until the end of 2017. After that either they'll slowly fade away, one by one. Or, if someone else wants to take over all or part of the series I'll happily pass over to them. I can even supply the tubes that are currently being used. BlaKids.

Welcome to the periodic table of the elements powered trail. There will be 113 caches to each represent each element on the periodic table (until new elements are added). For simplicity sake only elements approved by the “International Union of Pure and Applied Chemistry” will be included in this series.



The cache containers are small tubes as shown in the picture below


These containers have only a logbook inside them and no pen/pencil. Please make sure to bring a pen.

Selenium can be prepared with either an amorphous or crystalline structure. Crystalline monoclinic selenium is deep red; crystalline hexagonal selenium, the most stable variety, is a metallic grey (see picture above). Elemental selenium is relatively nontoxic and is considered to be an essential trace element. However, hydrogen selenide (H2Se) and other selenium compounds are extremely toxic, and resemble arsenic in their physiological reactions. Hydrogen selenide in a concentration of 1.5 ppm is intolerable to man. Selenium occurs in some soils in amounts sufficient to produce serious effects on animals feeding on plants such as locoweed (an American plant) grown in such soils. Source: Webelements.

This power trail starts at Mount Henry Bridge and continues south down the freeway cyclepath. This power trail is designed for bicycles or walkers and will be extremely hard, if not impossible for drivers. There is however a car park and a playground near the start.

Please stay safe and enjoy the power trail.
