Jonathan,

Here's one reference on a CCC camp:

"The Archaeology of a "Destroyed" Site: Surface Survey and Historical Documents at the Civilian Conservation Corps Camp, Bandelier National Monument, New Mexico" by Monica L. Smith
Historical Archaeology, Vol. 35, No. 2 (2001), pp. 31-40 

Also, I'd contact Carole Nash of James Madison University who has been excavating a CCC camp in Shenandoah National Park.  I believe she published on this work in the 2005 "Uplands Archaeology in the East" volume, but I don't have that handy at the moment.
