I remember, as a small boy, asking my father about huge rounded boulders, some the size of small houses, which were sitting in the fields of upstate New York.
He replied that they had been formed by being pushed ahead of advancing glaciers thousands of years before, and then , as the earth warmed and the glaciers retreated, the boulders were left behind.
Can you imagine that happening again now with all the big cities in the path of those glaciers ?!
Makes me glad I live in Texas... except this latest arctic cold wave went all the way down to Mexico.
