Point Location Description: Quarry
Location Method: Field Visit with GPS
Access Description: From the Town of Echo Bay, follow Highway 638 approximately 2.5 kilometres to the Echo Lake Road. Follow the Echo Lake Road past the north end of Echo Lake to a bridge crossing Upper Echo River. Continue on this road about 2.5 kilometres past this bridge to a Y in the road. The road to the right leads to the quarry about 550 metres northerly. The quarry is 2.3 kilometres west of the east boundary of Kehoe Township and 4.85 kilometres south of the north township boundary.
The earliest workings of the quarry took place about 1961 or 1962, the exact date is not known. There were some diamond drill holes put down on the property, but the core is not available. A company under the name of Special Aggregates Limited marketed the product in Michigan State. The quarry has had about 1400 tons of material removed over the years and is now inactive.

Dec 07, 2005 (P Beach) - A description of the quartzite is given by R. Rupert, former Resident Geologist in Sault Ste. Marie as follows: The quarry exploits a lens of green quartzite in a sequence of whitish to pale green, 10 foot thick beds of crossbedded indurated quartzite. Dips are 40 to 55 degrees south west. Petrographically, the quartzite is rather pure, being composed of 85% rounded and moderately sorted fine to medium packed grains of quartz and 5% rounded, fine to medium grained chert and jasper clasts. A few (less than 2%) decomposed feldspar grains are present. The above sand grains are in a matrix of very fine sericite flakes whose ends penetrate the quartz grains in a saw-tooth pattern when viewed microscopically. Frarey,1977 states that the Lorrain quartz arenite member dips toward a 200 metre thick, north west striking diabase dike. The dike is located in outcrop approximately 100 metres south west of the quarry site. Chromium-bearing micas are thought to give the green colour to the rock and it is suggested that fluid migration from the diabase, along bedding planes, has added chromium to the rock.
