Geocache Description:

This earthcache is located in scenic Albert Mines, New Brunswick. This community is named after the Albertine Mines which supported the community in the 1800's. Great quantities of Albertite was shipped south and used to light the lamps in the streets of Boston during the 1800’s, and the mines provided much profit and employment until the supply was exhausted less than 30 years later.

Albertite is a type of asphalt found in Albert County, New Brunswick. It is a type of solid hydrocarbon. It is a deep black and lustrous variety, and is less soluble in turpentine than the usual type of asphalt. It is the only solid petroleum source known. It was from Albertite that Kerosene was first created. Albertite is named after the Albert County Mines in New Brunswick, Canada, from whence it was first found. The occurrence at Albert Mines existed as a series of discordant veins which were hosted in the core of an anticlinal closure of a fold. It was initially mistaken for coal. The geologists of the 1800s were at a loss as to describe how this coal apparently came to lie discordant to the strata of the area, as they did not yet understand the nature of the oil shale source rock, nor the fact that the albertite was essentially solidified asphaltum.

Once on site, look around in the shale on the ground. You will easily be able to locate chunks of Albertite lying in the open. The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material.

In order to log this cache:

1. Test the hardness of a piece of Albertite by trying to scratch it with your fingernail (hardness 2.5) and a copper penny (hardness 3.5)

2. Send me the results of your Mohs scale test, and

3. Post a picture of some Albertite in your hand with your GPSr in your online log.
