Agate -- Rocks and Minerals Series #3

NOT RECOMMENDED AT NIGHT; THIS AREA IS RURAL RESIDENTIAL AND LIGHTS WILL ATTRACT ATTENTION. STEALTH REQUIRED.

BE SURE TO GET THE SINGLE DIGIT CLUE ON THE LOGSHEET FOR THE ROCKS AND MINERALS SERIES FINAL CACHE.

Welcome to the Rocks and Minerals Series, where you can learn a little about geology and find some caches at the same time. Each of the six caches named after rocks and minerals has a single digit on the logsheet that you will need to find the Rocks and Minerals Final Cache. For example, in the Ryolite cache, the Clue will be R = (some digit); in the Quartz cache, the clue will be Q = (some digit).

The final is at N 38 56.RQA W 105 17.FGP

Here are all seven caches in the series:

Ryolite (GC9NYB3)

Quartz (GC9NYB6)

Agate (GC9NYB8)

Feldspar (GC9NYB9)

Granite (GC9NYB7)

Pitchblende (GC9NYBA)

And then – Rocks and Minerals Final Cache (GC9NYBB)

From Wikipedia: Agate is a common rock formation, consisting of chalcedony and quartz as its primary components, with a wide variety of colors. Agates are primarily formed within volcanic and metamorphic rocks. The ornamental use of agate dates back to Ancient Greece in assorted jewelry and in the seal stones of Greek warriors. Use of beads necklaces with pierced and polished agate goes further back to the 3rd millennium BCE in the Indus Valley Civilisation. Agate is one of the most common materials used in the art of hardstone carving, and has been recovered at a number of ancient sites, indicating its widespread use in the ancient world; for example, archaeological recovery at the Knossos site on Crete illustrates its role in Bronze Age Minoan culture. Industrial uses of agate exploit its hardness, ability to retain a highly polished surface finish and resistance to chemical attack. It has traditionally been used to make knife-edge bearings for laboratory balances and precision pendulums, and sometimes to make mortars and pestles to crush and mix chemicals. It has also been used for centuries for leather burnishing tools.
