Geocache Description:

Welcome to the periodic table of the elements power trail - designed by BlaKids now maintained by multiple volunteers. The trail starts at Mount Henry Bridge and continues south, down the freeway cycle path. 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.

For simplicity sake only elements approved by the “International Union of Pure and Applied Chemistry” were included in this series.



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


These containers have only a logbook inside them BYO scribble stick.

Tantalum is a greyish silver, heavy, and very hard metal. When pure, it is ductile and can be drawn into fine wire, which can be used as a filament for evaporating metals such as aluminium. Tantalum is almost completely immune to chemical attack at temperatures below 150°C, and is attacked only by hydrofluoric acid, acidic solutions containing the fluoride ion, and free sulphur trioxide. The element has a melting point exceeded only by tungsten and rhenium. Source: Webelements.
