It was mysterious at the time, the South-western ruins having then not been discovered with one or two exceptions.

We ascribed this wall, however, to the ancestors of the Moki (Hopi).
In the afternoon as we pulled along we came to a small rapid and the walls by this time being closer together and growing constantly higher, we knew that we were now fairly within the Canyon of Desolation and for about one hundred miles would have a rough river.

Not more than two miles below our dinner camp we reached a locality where the stream doubled back on itself forming a vast and beautiful amphitheatre.

We could not pass this by without taking a picture of it and Beaman was soon at work with his apparatus while I got out my pencils.

The photograph did not turn out well, and Prof.determined to remain till the next day.
