Geocache Description:


I had the pleasure of working at the Georgia Pacific Facilities for a day to swap out some breakers. This is Georgia Pacific's Sheetrock plant. Sheetrock's main "ingredient" is Gypsum. Gypsum is a soft mineral composed of calcium sulfate dihydrate. It is a common mineral created in  lake and sea water deposits, as well as in hot springs and from volcanic vapors.

The Given Coords point to a giant silo full of gypsum in the back of the plant. A quick wikipedia search will get you the coords.

D) Sheetrock was introduced in 19D7
E) In 2015, Russia produced E,500 Metric Tons of Gypsum
