3/14: snow geese & a spirit mound

Our rambling today took us into South Dakota, and all along our route we saw snow geese flying overhead. Thousands upon thousands of them; I've simply never seen such complicated yet delicate wheeling in the sky on such a massive scale. And one of our destinations was a strangely shaped chalk hill which Lewis & Clark had visited and which Native Americans had told them was a home to little spirits. We climbed up the hill, and though we saw no little spirits we enjoyed the wind, the view, and the cries of the geese from above.
