They crossed into the United States, a fact discernible only because of a moss-covered boundary monument that one of the jihadists nearly tripped over. The falls were just ahead of them and to the right. They worked their way downstream of the falls by crossing a high shelf of rock that looked down upon it from its east side. This terminated in a cliff that obliged them to descend to the riverbank in order to make any more southward progress. As Richard now explained, there was a way to scramble down from here; there had to be, or else it would never have been possible to make the return trip. But when going in this direction, the descent was considerably easier if you just used ropes. Richard had warned Jones of this well in advance, and so Jones had made sure to bring some good long ropes along. They paused up there for a short while so that some could enjoy the view down while others, who were good at such things (or claimed to be) made the rope fast to a giant cedar growing near the edge of the cliff. Half the men went down to reconnoiter. Then they sent Richard. Then the rest of them went down. He got the sense that this had been carefully thought out; they were becoming nervous that he might make a break for it and wanted to make sure that there were a few people at each end of the rope to keep an eye on him.
