You got some interesting stuff there, Luck!
The scouts did military-like group training things where they may have clumped together for various activities.
A look around could identify where those spots are...
And caching... that would be a popular thing with young scouts... the caches may not be a hoard of gold bricks, but they would be intentionally interesting!
You will probably be able to locate different training areas a short hike out from the main center of activity.
