Gamma - A unit of measurement of magnetic intensity.
Geiger Counter - An instrument used in the search for radioactive minerals, particulary uranium, as it is capable of detecting (by means of a Geiger Mueller tube) the rays emanating from such minerals. It registers the frequency or intensity of these rays either visually (by dial or flashing light), audibly (by earphones) or both.
Geology - The science concerned with the study of rocks making up the earth.
Gold - A precious yellow metallic element, highly malleable and ductile, and not subject to oxidation or corrosion. Symbol: Au; atomic weight: 196.967; atomic number: 79
Greenhorn – A novice or inexperienced miner – usually given the least desirable jobs in the mining camp.
Guides - The timber along the sides of a shaft for the purpose of steadying, or guiding, the cage or conveyance.
Hanging Wall - The wall or rock on the upper or top-side of a vein or ore deposit.
Heading - A vein above a drift. An interior level or airway driven in a mine.
Highgrade - Rich ore – high in mineral content. ‘Highgrade’ used as a verb means the selectively mining the best ore in a deposit.
Highgraded - One who steals rich ore, especially gold, from a mine.
Host Rock - The rock containing an ore deposit.
Hydraulic - This describes a common method of mining in which water under pressure is used to cut away banks of gold-bearing gravels or overburden. Water is brought to the operation from a "head"; the water is then discharged into a pipeline, at the end of which is a nozzle called a "monitor" or a "giant".
Jackleg – A percussion drill mounted on a telescopic leg. The leg and the machine are hinged so the drill can point in the opposite direction. A hard tool to get the hang of – it works using a combination of drilling and water and is an essential tool in mining.
Jig - An apparatus used in milling to concentrate ore on a screen submerged in water, either by a reciprocating motion of the screen or by the pulsation of water through it.
Lagging - Planks or small timbers placed along the roof of a stope or drift to prevent rocks from falling, rather than to support the main weight of the overlying rocks.
Lamp - The electric cap lamp worn for visibility. Also, the flame safety lamp used in coal mines to detect methane gas concentrations and oxygen deficiency.
Lode - A mineral deposit in solid rock.
Loop – Glass magnifier used to determine rough mineral content.
Kristen sees the opening in the side of the mountain for herself and makes a startling realization about the way the mine aligns with Baker City.
At the Crescent, the men blast down the barriers in the mysterious drift and make an astonishing discovery, while Kristen and Stan confront a dark presence at the old Octave Mine in Arizona.
Stan and Eddie check in with mine owner Larry to outline their prospects for what little remains of the mining season.
