In short, the stability of the Taraco Peninsula settlement system
in the Tiwanaku period contrasts with the total reorganization experienced
by the Tiwanaku Valley and Katari Basin settlement systems at this
time. The latter systems were completely revolutionized by raised
field agriculture.
The Taraco Peninsula system was not. It retained the basic structure
that originated in the LF1, with the community boundaries and principal
villages essentially unchanged from the MF. This difference would
seem to suggest that the Taraco Peninsula was integrated into the
Tiwanaku state and economy in very different way from the other areas
of the core region. This statement is necessarily vague; I can be
no more specific. Were the Taraco Peninsula communities involved in
raised field production in the Tiwanaku Valley and the Pampa Koani?
Or were their state labor obligations of a wholly different nature,
involving dryland agriculture or non-agricultural activities? The
question of the peninsula's relation to adjacent areas, and the nature
of Tiwanaku state tribute extraction, clearly merits further research.
