The EF2 settlement distribution was clearly unimodal, and the MF one
was just as plainly bimodal (Figure 6.9). The
LF1 settlement hierarchy, however, is more complex. The LF1 settlement
distribution, shown on Figure 7.6, clearly
displays two tiers of smaller sites. The smallest group consists of
sites with population index values of less than 200, and the second
group of sites have population index values between 200 and 500. However,
there are two sites which are much too large to belong to either group.
The larger of the two is Kala Uyuni (T-232), with a LF1 population
index value of 883. The smaller is Kumi Kipa, with a population index
of 647. Both of these sites grew much faster than any other sites
on the Taraco Peninsula during the LF1 (see Figure 7.8a
for a graphical representation). In fact, the growth rates of each
exceeds the probable natural rate of increase, suggesting that considerable
numbers of people moved to these locations from other villages on
the peninsula. T-232 grew at an annual rate of 0.17% during the LF1.
No growth rate can be calculated for T-272, since its has no MF occupation.
However, the Santa Rosa group as a whole (T-268/T-271/T-272/T-322)
grew at an annual rate of 0.29%![[*]](file:/usr/share/latex2html/icons/footnote.png){kind=icon}
in the LF1.
What then is the relation between the Santa Rosa group and Kala Uyuni?
My proposal, which must await evaluation by future excavations, is
that the two are more sequential than contemporaneous. Put plainly,
I believe that Kala Uyuni grew very rapidly in the earlier part of
the LF1. At this time, the Santa Rosa group consisted probably of
only Sonaji (T-271), then a small village relocated from the nearby
MF site of Sunaj Pata (T-268). At some later point within the LF1,
Kala Uyuni was almost completely abandoned, and the bulk of its population
was relocated to the Santa Rosa group. This population relocation
accounted in part for the very rapid growth of the Santa Rosa group.
This scenario is lent further support by the fact that Kala Uyuni
has large MF and LF1 occupations, but almost no LF2 occupation, while
the Santa Rosa group was very small in the MF, but a major population
center in the LF1 and LF2 periods. The site size distribution presented in Figure 7.6
therefore represents the superposition of two sequential settlement
hierarchies within the LF1 Period. Both of these hierarchies had three
tiers of sites. The earlier had its center at Kala Uyuni, and the
second at Sonaji/Kumi Kipa.
