You asked about the Blue Ridge but mostly got beta on WV stuff so here's some VA/Blue Ridge sources:
has some pics of Statons Creek which would be the most likely creek to run.
has write-ups on Statons, The Forks of the Tye, SOuth Piney, "BC", etc. which are in the class V range.
Goshen Pass of the Maury RIver is a fun class III river that runs off less rain than the above creeks. It is beautiful and actually very Colorado like I think.
