Hey Frank that looks like a serious amount of work. I'm very new to all this and have a question for you. The roots that are showing is that it? Or have they been cut off some? Wow and I thought raking leaves and pruning some trees back was alot of work!
Good luck on your relic hunting. I have an older model Whites machine and have done alittle searching. Sounds like you have found a nice area to hunt if your spending 6 days there. Most of my detecting has been in older parks for silver coins. The best place I have found was Fairmount Park in Philadelphia, the oldest city park in the US. Unfortunately they won't let us in there anymore with detectors.
I also have a soft spot for the CW. I belong to the N-SSA an organization primarily for those interested in competative black powder shooting of CW original and replica firearms and keeping the history alive, lots of fun. If your interested

I hope to plant some Musa Basjoo next spring along with other tropicals right now I'm working on the soil. Good luck next week, hopefully the yellow jackets and hornets are resting. Kurt in SE PA...
