VT is where glaciers went to die. I believe there were staggering deposits of rock when glaciers melted after the Ice Age.
Adding to glacial deposits, I live in a steep valley where a high speed, (lots of vertical) stream flows. Each major flood event brings millions of tons of rock down from the mountain. One storm washes boulders away, next brings in more.
I paid for years to have them hauled away, then I bought machinery. My wife says rocks are my hobby. I pile them ever higher to make space between them. I'll get pictures.
Years ago a contractor was hired to surround 22 handicapped outhouses in the National Forest. While there are billions of boulders in the National Forest locally, he wasn't allowed to use them. Each outhouse was to have 25? 4' boulders in a circle surrounding it.
The contractor came to me. I said "Knock your socks off. Take all you want."
I came home after he left. My father was around at the time, I asked: "Why didn't he take any?" He said: "He took 7 tandem loads." I couldn't see a change!
If you pay for a rail car, I'll fill it free.
