Following the return of the main party to Washington, some preliminary
exploration was carried on by Mr. E. W. Nelson, who made an examination
of the headwaters of the South Fork of Salt River, but did not find any
ruins. Thence the Blue Ridge was crossed, and the valley of the Blue
Fork of the San Francisco River visited. Here ruins were frequently
increasing in number toward the south. Farther south three sets of cliff
ruins were also located.
