Discussion: depressions

do you think they are natural or could they be bomb craters?

I assume all were bomb craters from roughly 70 years ago. You see reminders of the wars in lots of places -- trenches in northern Italy and France, bomb craters in Germany, cemeteries out in the middle of nowhere, unmapped anti-tank defenses in Switzerland. All sobering.

What in the world was the feature for #8?

Clue symbol was veg boundary, but a more appropriate symbol would have been a square witha line through it.

I would have said the feature, presumably, was "center of the circle."

Aka bag in the woods.

According to the bulletin notes about the map, the depressions are from the extensive mining in the area.

I saw that, but it seemed like there would have been more signs of mining in the area. The lakes and ditches all made sense, but it didn't seem like there were any signs -- if those were mining holes -- that any of them had been successful finds. No more substantial digging.

Of course, if they were bomb craters, doesn't seem like they were successful either.

I think it possible that they were bomb craters and the organizers didn't feel like saying so. But that's just a wild guess.

Back at WUOC in 1996, the terrain was covered with tank excavations... which were kind of cool.

I'm not sure that Peter's and Charlie's theories are incompatible.

If there were mining deep underground than maybe all the little depressions could be "sink holes" were water has washed soil down into the mind causing a sink hole or depresson on the surface. I think there is some of this in the Allentown, PA area but I would have thought the depressions would have been quite a bit bigger.
