Geological / Topographic features of Pennsylvania
Geological / Topographic features of Maryland
This is an interesting publication from 1965 that I took off of microfiche from the Maryland Geological Survey. Its Bulletin 28 and for people that live in Carroll and Fredrick county Maryland, most don't realize that they live in what was a very active mining area that was producing many heavy metals including gold. I lived in the Sykesville, Maryland area from 1988 to 1996 and explored many of these mines. The best preserved area was on and just north of the Fairhaven Nursing Home along the banks of Piney Run. We would park along RT32 and head west. The mines were obvious and it was not hard to remain undetected by the residents of Fairhaven.
Another interesting area was just east of MD-32 (Sykesville Road) where it crosses Liberty Reservoir. Although being on public accessible land and because of that this area has been picked thru, you can still find some interesting minerals in the spring and after heavy rains.
More old mines are located where Maryland 140 crosses Liberty Reservoir and you can find tailings on both sides of the road on the west side of the reservoir. Again this was 25 years ago and I am sure road expansion and utility work has destroyed many of these sites. Refer to the maps in the bulletin to try to figure out what is left
