Petroglyph Mine location

The Petroglyph Mine is located, in the Hillsboro Mining District east of Hillsboro.  On the detail from the Hillsboro Geologic Quadrangle (right) the shaft is at the head of the white arrow.  mindat.org gives the location of the mine as: Latitude & Longitude (WGS84): 32° 56' 2'' North , 107° 32' 39'' West OR Latitude & Longitude (decimal): 32.9338888889, -107.544166667. It is undoubtedly named after the petroglyphs and bedrock mortar holes (see photo below) which are nearby. 

Like many mines in this area, this mine has been called by various names - in this case, this mine is also known as the Miners Dream Mine.  Lots of mine names indicate the wealth to be had - even though that usually was not the case.

Among the minerals taken from this mine are: Anglesite, Aragonite, Baryte, Calcite, Cerussite, Descloizite, Goethite,Hemimorphite, Melanotekite, Mimetite,   Mottramite, Quartz, Vanadinite, Arsenatian Vanadinite, Wad, Willemite, and Wulfenite.  A specimen of Vanadinite, taken from this mine is shown below.

Photographs of the Petroglyph Mine shaft are shown above and below.   mindat.orgdescribes the mine as: “Workings visible from the surface (January 2008) include a small inclined opening on the south end, which quickly drops vertically (ladder length deep). A shaft, of unknown depth, is located not far to the north and a second shaft is open in line with the other two openings. Overall, the length of the area containing the openings is about 100 feet (30 meters), or less. The surface around the northernmost opening has the remnants of a small ore pile on its western side. The overall footprint of the mine is barely visible from the highway despite the fact that it is near the top of an open hillside.”
