Janusek dates the LF2 from 300 A.D. to 500 A.D. ([Janusek 2002]). I have retained these dates in the present analysis.
Considered in ceramic terms, the shift from LF1 to LF2 consisted of the gradual disappearance of the Kalasasaya red-rimmed bowls, the abrupt replacement of the Kalasasaya zoned-incised complex with a new set of decorated ceramics grouped under the name ``Qeya'', and a partial change in plainware pastes.
I consider three groups of ceramics to be diagnostic for the LF2. They are:
Qeya polychrome ceramics were formally defined by Dwight Wallace ([Wallace 1957]). Wallace characterized them as having a fine, light-colored paste, sometimes micaceous, unslipped and painted in a variety of colors. Qeya ceramics also exist in a variety of unusual forms. From the perspective of the survey archaeologist, however, Qeya polychrome ceramics may be summarized simply as ``polychrome on unslipped buff''. Fragments of these vessels are quite rare on the surface, and they seem to be restricted both regionally and locally (that is, on both the intra- and inter-site scales), as was the case in the LF1. Examples recovered from the survey are illustrated in Figure 7.1m-q.
In addition to the polychrome on buff sherds, some black on red sherds
are also present in this phase (see [Albarracín-Jordan 1996a]: 131 and Figure
7.7; Figure 7.1r-s).
One yellow on black rim was recovered which is probably LF2 in date
(Figure 7.1t). These sherds do not fall within
Wallace's definition of Qeya, but they do seem to pertain to the LF2.
Qeya incised ceramics were also identified by Wallace. These sherds
display a very closely-spaced pre-firing incision, typically comprised
mostly of parallel lines. This is a very widely distributed style,
having been found in the Tiwanaku heartland ([Bermann 1990]:
Figure 77b, [Bermann 1994]: 135, Figure 9.5b; ), in the Juli area ([Stanish and Steadman 1994]),
at Camata ([Steadman 1995]: 392, Figure 70d), on the Santiago de Huatta
Peninsula ([Lémuz Aguirre 2001]: Figure 8.60d-f), and in the northern
Titicaca Basin and as far away as Cuzco ([Chávez 1985]). They are even
more rare than Qeya polychrome ceramics. Only one example was recovered
during the survey (Figure 7.1u). Flattened
or ``shelf'' rims incised with parallel or zig-zag lines appear
to be distinctive of this phase as well (see Figure 7.2p;
also [Burkholder 1997]: 170 and Figures 6.10, 8.2), as do lobes
on the rims of hyperboloid bowls, incised with 2-4 parallel lines
([Lémuz Aguirre 2001]: Figure 8.55a-b).
Since Qeya polychrome and Qeya incised ceramics are so rare, they cannot be used to reliably define LF2 occupations in Taraco Peninsula sites. For this purpose it was necessary to identify a plainware ceramic paste distinctive of the phase. Paste Group 13 serves the same purpose for the LF2 as Paste Group 6 did for the LF1.
Paste Group 13 consists of thin, reduced sherds, brown to dark gray
in color, mostly of cooking ollas, which are tempered with a great
quantity of mica. The density of mica in these sherds is very high,
and may be considered distinctive of the phase. Paste Group 13 did
not comprise the majority of the LF2 ceramic assemblage. However,
it was sufficiently common to be useful as a temporal marker in surface
collections. For example, Janusek found that a ``brown'' paste
and a ``dense mica'' temper characterized 14% of the LF2 assemblage
at the site of Kirawi on the Pampa Koani. He also notes that at this
time ``ollas with thin walls and high densities of fine mica became
common'' ([Janusek 2002]). A similar pattern may be observed
at Tilata, in the Tiwanaku Valley. Further, Mathews notes that the
blackware of the ``Kallamarka style'' ([Portugal Ortíz and Portugal Zamora 1977]: 260) represents
``a probable Tiwanaku III domestic ware'' ([Mathews 1992]: 223).
This last assemblage may or may not correspond to what I have termed
Paste Group 13. Finally, Carlos Lémuz has stated that nearly 20%
of LF2 (his `Pana Tardío' phase) ceramics on the Santiago de Huatta
Peninsula can be classified as his Paste 12, which is ``very dark''
and contains significant quantities of mica ([Lémuz Aguirre 2001]: 159).
Summarizing the LF2 ceramic evidence, I am forced to admit that this
phase is the most tenuously identifiable. The truly diagnostic ceramics
(the Qeya polychrome and incised wares) are very rare indeed. The
only apparently diagnostic plainware type (Paste Group 13) is uncommon,
comprising - if I may extrapolate from Janusek's excavation data
- no more than 10-20% of the total plainware assemblage. I believe
that my definition of the phase has been adequate to satisfactorily
identify LF2 occupation components using mixed surface assemblages.
However, it is abundantly clear that much more work is required and
that the LF2 is the most problematic phase in the regional sequence.
