mega-drought” throughout the Southwest in this century, comparable to that which destroyed the Ancestral Pueblo culture.
Ancestral Pueblo people abandoned their communities by about ad
1300, the time that marks the beginning of the fourth Pueblo period. It
is believed that a convergence of cultural and environmental factors
caused this to occur. The Great Drought
(1276–99) probably caused massive crop failure; rainfall continued to
be sparse and unpredictable until approximately 1450. At the same time,
and perhaps in relation to the Great Drought’s impact on the
availability of wild foods, conflicts increased between the Ancestral
Pueblo and ancestral Navajo and Apache groups. During the Pueblo IV
period, the Ancestral Pueblo moved to the south and the east, building
new communities in places where gravity-based irrigation works could be
built, including the White Mountains of what is now Arizona, as well as
the Rio Grande valley. Although some new villages were even larger than
those of Pueblo III, they tended to be cruder in layout and construction
than their earlier counterparts; stone was used less often, and in some
cases construction materials consisted wholly of adobe. The production
of fine pottery continued to flourish and develop, however, as did
weaving.
