While I was in Southern California for work in December '08, I took an Arizona run during the few free days I had. This was a day trip to Meteor Crater, the site of a very large meteor impact. It was so windy I got lifted off my feet when I tried to go up to the lip of the crater. That was totally sweet.
Yes, that itty bitty rock that this view scope is pointed at is the size of a house, giving you a relative idea of the size of the crater.
