Jesse Walter Fewkes,
Preliminary report on a visit to the Navaho National Monument…
“ In stretches where the stream almost washes the bases of the ruins there could have been no extensive farming lands. The creek meanders through the soft clay and sand which fill the valley to the depth of many feet, forming treacherous banks that are continually falling and changing the course of the stream, so it is quite possible that the present configuration of the valley is very different from what it was when the cliff-dwellings were inhabited. If the occupants once had farms within its limits all traces of them would have long since been obliterated. ”
