The Western Maryland (Gold)

[RealBigSwede]

Hello Like to know if it is gold in the Garrett county, MD? I read some where that the first gold rush in USA was in Potomac river. If that is true can you still find gold in the upper Potomac river. the other question is can you find it with metal detector or do you have to use a wash pan?
Thanks in advance,

The head of the Potomac River is in coal country. What was found was most likely pyrite or fool's gold.
