A couple other reports that may address this issue (unfortunately, I no
longer appear to have copies of these).  Mark Branstner's report deals
with surface features at the CCC camps, but he may have observed alcohol
bottles or came across historical documentation as well - Mark are you
still on the list?

Their is a CCC museum in Michigan as well that may have additional
information on this topic (see link).
