s. One ofthese occurs at a point just west of that shown in the section. About80 feet east of that point the ditch makes another turn southward, andabout 40 feet beyond strikes the face of the bluff almost at right anglesand passes under it. About 50 feet north of the main ditch, at the point where it passesunder the bluff, there are the remains of another ditch, as shown onthe map. This second ditch was about a foot higher than the rnaiustructure, or about 4 feet above the river; it runs nearly parallel withit for 30 feet and then passes into the bluff with a slight turn towardthe north. It is about the same size as the main ditch, but its sec-tion is more evenly rounded. Figure 300 shows this ditch in section. As already stated, the American ditch is about 14 feet above theriver, while the ancient ditch is less than 4 feet above the water.

The waterthat flowed through the modern ditch was taken from the river at apoint about 3 miles farther northward, or just below Verde. The waterfor the ancient ditch must have been taken out less than a mile abovethe southern end of the section shown in the map. At first sight it would appear that the ancient ditch antedated thedeposit of alluvial soil forming the bottom land at this point, and this
