Hi cen1- Another newbie here... A quick search at Google Books found this out-of-copyright text regarding gold in your area. Found in US Geological Survey Bulletin #59, dated 1889. You can probably find more at http://books.google.com/advanced_book_search by trying various keywaod searches "Pennsylvania" and "Gold". http://books.google.com/advanced_book_search ------------------ Found in the US Geological Survey Bulletin #59, dated 1889. GOLD NEAR THE GLACIAL MARGIN. A few words should be said respecting the frequent discovery of gold near the glacial margin, since it is so often the cause of serious delusion. The whole region covered by my special investigations and lying west of the Blue Ridge in Pennsylvania, is covered with stratified deposits of the Upper Silurian, Devonian, and Carboniferous ages. So little disturbed are they that it would be hopeless to look for gold in them. The natural explanation, then, of finding gold any where in this region would be that it was a part of the glacial transportation from the granitic region to the north. I soon learned from experience that tho gold diggings were sure to be located near the glacial margin, where it might be supposed that the till had been most weathered and washed, and which had, presumably, been skimmed from the disintegrated surface of the northern rocks on the first advance of the glacier over them. In this border gold has been found frequently in quantities to repay a moderate expenditure in washing the gravel, but never in large quantities. I found such deposits in Brown County, Indiana (and indeed in all the southeastern counties of Indiana), in Brown, Clermont, Licking, and Knox Counties, Ohio, and in Lycoming County, Pennsylvania In all cases them deposits are within the glacial boundary, and are near the glaciated margin.
