Seneca
Mine Dump
On
Friday morning the trip was to the Seneca Mine dump. As I understand it, this
dump was used by the Seneca #2 and Seneca #3 Mines. The dump is easy to get to.
From US 41, go west on First St. in Mohawk for 0.3 miles to a red gate on the
left. I don’t know if this dump is always open for collecting. The gate would
seem to suggest not. In any case, for the record, the GPS coordinates of the
dump are Lat. 47 deg. 18.703’, Lon. –88 deg. 21.844’.
The
piles here are not very steep, so collecting is easy. I found a lot of epidote,
both lining vugs and as individual crystals perched on red microcline crystals.
There were also nice clear quartz crystals and sprays of pumpellyite-(Mg). I
also got a couple of specimens of saponite in white crystalline balls, and a
few copper crystals. There was also a fair amount of massive copper.
On to the next field trip, the
