Talk:Carbaugh Run Rhyolite Quarry Site

Unsourced text
The following text was added by an IP to the lower part of the article:"A study was conducted on the quarries by Dr. Kurt W. Carr of the Pennsylvania Historical Museium Commission in the nineties so he could write a book of the findings, but never completed the book, thus it never made it to the shelves. Carr discovered that the mines were mined for around 11,000 years, starting in the Paleo-Indian Period around 9,500 B.C.E."Because no sources are provided, I've removed it: we can't use an incomplete and unpublished book as a source, even if it were properly cited. Assuming that the person using the IP knows what s/he is talking about, this is nevertheless useful information that shouldn't be left buried in the page history.
