Cornwall Quarry Tailings, Cornwall, PA
November 6, 2016 (Sunday)
The Cornwall iron mine is the largest iron deposit in the US east of the Minnesota Mesabi range. It was mined from 1732 to 1972 both as an open pit and underground mines with more than 100 million tons of ore recovered. The big pit was flooded by hurricane Agnes in 1972. The mines were subsequently closed and blasted, which formed several lakes on the golf course. There are many tailings piles in the area and we visited several over the past 4 to 5 years.
We can expect to find many minerals and interesting rocks
(see site geology and mineralogy below).
For those interested in this trip I recommend spending a few
minutes doing an internet search….many interesting and informative
articles are available.
