“Coming back we passed a great glacial basin full of smooth moraine.
“Think! cried the Professor.”This prodigious bowl was filled with ice to a depth of three hundred feet. And when we and our children are dead, seeds will have sprouted in the silt, and a young forest will nod over these stones. Here before you is one scene of a geological drama, past and furture implicit in the present you perceive, and all within the span of a single human generation, and a human memory.”-Oliver Sacks
