>What is the title of this book?
Sorry. Jenkins, R.E. and N.M. Burkhead. 1993. Freshwater fishes of Virginia.
American Fisheries Society, Bethesda, MD. 1079pp.
ISBN 0-913235-87-3. It's kind of pricey, but worth every dollar- it's
probably worth 2-3x what the going rate is now.

Agreed. With the lowered water temps afforded by tree cover, brook char
certainly occupied areas much farther down the mainstem than now- probably
well past Cumberland.

Maybe. There's a bunch of palaeo-zooarchaeological sites along the Potomac,
but I don't know what the composition of fish taxa is like in them- haven't
searched the literature. Certainly things like Semotilus pharyngeal arches
and Ameiurus spines would be relatively long-lasting and easy to ID...
cheers,
Dave
