It's entirely possible that at the point in time I stumbled over them, I and the caretaker I commented to were the only people in camp who knew there were graves there. Scouts were forbidden from the area, as it was near the maintenance shed and there was heavy equipment about, and the only reason I noticed them was that I tripped and fell on them. Otherwise, it just looked like rocky ground. These were natural rocks, not shaped in any way, nor were they arranged in any regular fashion. The inscriptions were only visible on very close inspection and were partially buried. I should talk to my dad about it.
