Subsistence
by Kristin A. Kuckelman
1
In this chapter, I address the means by which the villagers of Yellow
Jacket Pueblo (Site 5MT5) obtained the necessities of life such as water,
food, shelter, fuel, and raw materials for tools. Evidence of subsistence
practices at Yellow Jacket includes the remains of plants, animals, structures,
tools, and pottery. As is typical of prehistoric Pueblo peoples studied
elsewhere in this region, the occupants of Yellow Jacket Pueblo exploited
a wide variety of materials for survival. Here, I draw on information
presented in several other chapters in this publicationspecifically,
"Artifacts," "Archaeobotanical
Remains," and "Faunal Remains"to
further our understanding of the villagers' use of the resources in the
surrounding environment. I also present inferences about the management
of ancient water resources and the use of stone in construction at the
village.

Basic physiographic and geographic descriptions of the site are contained
in The
Yellow Jacket Pueblo Database under the heading "Site-Wide Data."
A great deal of additional information has previously been published on
various aspects of the environment of the Yellow Jacket area, including
soils (Brown 1975*1; Stevenson
1984*1), geography (Yunker
2001*1), geology (Brown 1975*1;
Stevenson 1984*1; Yunker
2001*1), lithic resources (Arakawa
2000*1), climate (Adams and
Petersen 1999*1:Tables 2-2, 2-3, 2-4; Brown
1975*1; Lange et al. 1986*1;
Stevenson 1984*1), plants (Brown
1975*1; Cater 1989*1; Stevenson
1984*1), animals (Brown 1975*1;
Cater 1989*1), and historic
uses of the area (Connolly 1996*1;
Lange et al. 1986*1).
Water Resources
3
Water is the most essential of all subsistence resources. A reliable and
abundant water supply would have been necessary for the founding and survival
of a village the size of Yellow Jacket, for the village housed an estimated
1,360 residents during its population peak (see "Population
Estimates"). Water would have been necessary for drinking, cooking,
pottery making, washing, and building construction and also could have
been used for irrigating gardens and crops. Although the climate is semiaridthe
Yellow Jacket area now receives an average of 41 cm (16 in) of precipitation
annuallythe ancient villagers had ready access to multiple seep
springs in the two drainages that form the east, west, and south edges
of the site. One additional spring on the canyon rim was enclosed by the
great tower complex (Architectural Block 1200) late in the occupation
of the village.
4
In historic times, these springs were some of the most dependable in the
area and were relied upon by early settlers (Connolly
1996*1:10). The main Yellow Jacket spring at the east edge of the
site was reputed to have the "best" water in the area and was a well-known
watering hole for travelers on the Spanish Trail (Connolly
1996*1:10). In the late 1800s, this spring was also used as a watering
stop by a stage line that ran between Dolores, Colorado, and Monticello,
Utah (Lange et al. 1986*1:1).
These springs would have been crucial for the survival of the ancient
village at Yellow Jacket, and the productivity of these water sources
could well have established an upper limit to the size of the village.
5
Water-control features were built to slow runoff and water from the seep
spring enclosed by the great tower complex. A series of one definite and
three possible dams spanned a shallow drainage bisecting this complex
(see paragraph 36 in "Architecture")
and served to slow the flow of water from the uplands into the canyon.
In addition, a reservoir might have been formed by a north-south-trending
berm of earth and stone located at the west edge of a large depression
(Block 2000; see Database Map 263). The function of this possible
dam and the associated depression could not be confirmed from our limited
testing. The characteristics of the depression and dam are similar to
other features in the region that have been interpreted as reservoirs
(Wilshusen et al. 1997*1),
but no water collected in this depression at any time during our three
seasons at the site, which included some very wet, spring weather and
summer thundershowers. Our testing revealed that the sediment within the
depression contains artifacts down to bedrock; thus, bedrock was exposed
within at least some portion of the depression during the occupation of
the village and would have improved the ability of this feature to collect
and hold water. Alternatively, the area of the depression and exposed
bedrock might have been a plaza (see Ferguson
and Rohn [1986*1:129] and paragraph
165 in "Artifacts," this publication), with the berm at the west edge
serving to complete the enclosure of this public space.
Building Stone
6
Yellow Jacket Pueblo was built of local sandstone that appears to have
been brought out of the adjacent canyons and draws. Many of the stones
had been shaped to form more-regular blocks, and some faces had been pecked,
presumably for aesthetic reasons. I estimate that 103,000 stones were
used in the construction of the 195 standard-size kivas at this site (including
stones used in pilasters but not in deflectors or ventilation systems).
This estimate assumes an average bench-face-to-bench-face diameter of
3.6 m, a bench height of 1 m, an upper-lining-wall height of 50 cm, and
a bench width of 30 cm. Using information from our test excavation of
kivas in the great tower complex, I also derived an average number of
stones per square meter for each of these types of walls. It was not possible
to estimate the number of stones used to construct the 600 to 1,200 rooms
at the site, because of the great variability in both the size of the
rooms and the masonry techniques used (for example, double-stone vs. double-stone-with-core);
however, a very rough guess of the total number of stones used for construction
at Yellow Jacket Pueblo would be between 500,000 and 1 million. The labor
required to collect and transport this many stones from nearby talus slopes
and canyon bottoms would have been nothing less than monumental; the additional
time required for rough shaping, dressing, and laying this many stones
would have been substantial as well. Under circumstances roughly similar
to those at Yellow Jacket, Varien
(1984*1) estimated that 52 stones could be gathered and transported
per hour per person; if this estimate is accurate, it would have taken
one person working eight hours per day between 3.3 and 6.6 years to collect
and transport the number of stones used in the structures at Yellow Jacket.
The removal of this many stones from the canyon almost certainly would
have been noticeable visually, although it is difficult to say whether
any adverse effects on the environment would have resulted.
Plant Resources
7
Near the village, a wide variety of wild plants would have been available
on the uplands and talus slopes and in the canyon bottoms. Numerous species
grow in the area today, and most were also available in ancient times.
The primary vegetation on the site today is sagebrush. Other vegetation
in the vicinity of the site includes pinyon and juniper trees, ponderosa
pine, Gambel oak, chokecherry, serviceberry, rabbitbrush, globemallow,
sego lily, ricegrass, scarlet gilia, tansymustard, lupine, broad-leafed
yucca, willow, cottonwood, gooseberry, mullein, fern, yarrow, and a variety
of cacti.
8
Plant remains found during our testing indicate that many plants were
used by the ancient residents of Yellow Jacket Pueblo (see "Archaeobotanical
Remains"). Wild plants used for food include the seeds of cheno-ams
and various parts of groundcherry, yucca, purslane, bulrush, ricegrass,
and hedgehog cactus. Juniper, sagebrush, pine, oak, serviceberry, rabbitbrush,
Mormon tea, cottonwood/willow, wolfberry, cliff-rose, saltbush, and chokecherry/rose
were used for fuel. Specimens collected during our testing indicate that
juniper was the wood most commonly used for constructing roofs. Other
construction woods found include sagebrush, pinyon pine, ponderosa pine,
and Douglas fir. Although ponderosa pine has been identified in the vicinity
of Yellow Jacket Pueblo (Stevenson
1984*1:Table 1), this species is rare in the area today, and the timbers
represented by the specimens collected during our testing might have been
brought to the site from a substantial distance. Yellow Jacket is too
low in elevation for Douglas fir to grow (Adams
and Petersen 1999*1:Figure 2-5). The nearest stands of this species
are in the Dolores River canyon, approximately 8 km northeast of the site,
so this wood might also have been transported a significant distance for
use in construction at the village.
9
Recent research on methods of kiva-roof construction (Hovezak
1992*1:68) indicate that between 96 and 192 timbers were needed to
roof one standard-size, six-pilaster kiva. If this is correct, roof construction
for the 195 standard-size kivas at Yellow Jacket Pueblo would have required
between 18,720 and 37,440 beams. The amount of labor required to procure
and transport this many beams is daunting by any measure, and the impact
on the landscape would have been significant. Also, the above estimate
does not include timbers used for the roofs of the estimated 600 to 1,200
rooms constructed in the village. Although it is likely that some beams
were salvaged from abandoned structures in the dispersed community and
within the village itself, most beams would have been newly harvested,
especially during the building surge in the late A.D. 1100s and early
1200s.
10
The remains of domesticated plants were also found during our testing
and indicate that the villagers at Yellow Jacket Pueblo grew and ate maize,
beans, and squash, the domesticated crops typical for this culture and
time. The presence of maize shank and stem parts in several locations
at the site indicates that maize fields were near the village (see paragraph
55 in "Archaeobotanical Remains"). To the north, west, and east of
the site today are cultivated fields in which alfalfa, wheat, and pinto
beans are grown (some dryland, some irrigated). Historically, these areas
were covered with sagebrush and scattered stands of pinyon and juniper
trees before they were cleared for cultivation. The soils are deep, well-drained
loess that would have been good for the practice of ancient horticulture.
Crops would have prospered, given an adequate amount of moisture and a
sufficiently long growing season, neither of which could be taken for
granted on this high (2072 m), semiarid plateau. According to Adams
and Petersen (1999*1:49), the Four Corners region in general is "near
the northern and upper elevational limits of where rainfall farming of
maize can take place"; it is believed that such was the case during the
Pueblo occupation as well.
Animal Resources
11
Animals provided the villagers at Yellow Jacket Pueblo with many subsistence
necessities, including meat, hides, sinew, bones, antlers, feathers, and
eggs. These materials would have been used for food, tools, weapons, blankets,
clothing, and ritual objects. Animals observed today in the Yellow Jacket
area include lizards, mice, squirrels, chipmunks, ground squirrels, prairie
dogs, cottontail rabbits, jackrabbits, foxes, coyotes, mule deer, mountain
lions, and a wide variety of birds.
12
A large number of animals are represented in the assemblage of animal
bones collected from the site (see Table
2 in "Faunal Remains"). As is usual for Pueblo II and Pueblo III faunal
assemblages in the Mesa Verde region, domestic dogs and turkeys were the
only two domesticated animals represented. The bones of turkeys and rabbits
are the most numerous in the entire assemblage, as is also typical. The
quantity and distribution of bones from these two types of animals at
the site suggest that the flesh of these animals was frequently consumed,
as were probably turkey eggs. Also typically, artiodactyl (primarily deer,
but also pronghorn antelope, elk, and mountain sheep) remains are much
less numerous and become progressively more scarce in later deposits,
with one exception. More artiodactyl bones were recovered at the great
tower complex, which was probably one of the last constructions at the
village, than from other architectural blocks, suggesting that this block
was either used differently or abandoned differently from other blocks.
Increased frequencies of artiodactyl remains at structures that might
have served specialized functions or might have been the locations of
unusual abandonment activities were also noted at Sand Canyon Pueblo (see
"Faunal Remains").
Pottery and Tools
13
The use of pottery to date the occupational history of the site is discussed
in both the "Artifacts" and "Chronology"
chapters. Other inferences drawn from pottery data relate to production
and trade of pottery vessels. Evidence of pottery production was found
in most tested areas of the site (see paragraph
95 in "Artifacts"), indicating that pottery was probably produced
in most or all architectural blocks in the village. There are also indications,
however, that pottery production might have become more centralized during
the A.D. 1200s. Additional possible evidence of specialization was noted
in the proportions of artifact types in different architectural blocks
at the site; it is possible that residents in peripherally located blocks
tended to specialize in certain tasks more than did residents of centrally
located blocks (see paragraph 168
in "Artifacts"). These indications of possible economic specialization
within the village might have important implications for our understanding
of the social and political systems, as well as of the spatial organization,
of the village.
14
The frequency of imported pottery is low in the Yellow Jacket assemblage.
It is particularly low in the great tower complex, which might reflect
a decrease in pottery importation during the final decades of regional
occupation or could indicate that this architectural block was used for
some special activity or activities. In addition, sources of imported
pottery appear to have shifted through time. Before A.D. 1180, most of
the nonlocal vessels came from the western Mesa Verde region, in what
is now southeastern Utah. After A.D. 1180, most of the imported pottery
came from the Kayenta region, now northeastern Arizona. Ortman (paragraph
119 in "Artifacts") infers that the changes in these frequencies through
time might have been dictated less by changing preferences of the villagers
than by the level of production of the vessels, reflecting changes in
population size through time in the regions where the vessels were produced.
Most stone tools found at the site were of materials that are available
locally. Tools of semilocal and nonlocal raw materials were also found;
however, the frequency of these tools appears to have decreased through
time in the village. These indications of generally lower levels of trade
during the final century of occupation of the region have been documented
in assemblages from other sites as well (see paragraph
158 in "Artifacts").
15
Several types of tools were also fashioned of animal bone and antler,
including awls, needles, scrapers, and pressure flakers. There is some
evidence that fewer bone tools might have been produced through time in
the village; however, it is equally likely that this apparent decline
resulted from the removal of numerous bone tools from the great tower
complex during excavations by the Museum of Western State College in 1931
(see "Architecture").
16
Many objects of personal adornmentpendants, beads, and tubeswere
found at Yellow Jacket Pueblo. Most of these objects were made from raw
materials available locally. These objects were found in virtually every
architectural block tested, and most were in secondary refuse. Like the
frequency of imported items, the frequency of ornaments appears to have
decreased through time.
Conclusions
17
The Yellow Jacket villagers made extensive use of resources available
in their natural environment for food, building materials, fuel, and tools.
In addition to using many wild plants and animals, they raised crops and
kept domesticated turkeys. Yellow Jacket Pueblo is located in the Monument/McElmo
drainage unit, which has high agricultural and foraging potential (Adams
and Petersen 1999*1:Figure 2-1, Table 2-7). The proximity of water
was undoubtedly a key factor in the impressive size and longevity of this
village. The collection of enormous numbers of stones and timbers for
use in construction must have noticeably altered the surrounding landscape.
The artifact assemblage from the site indicates that, through time, trade
decreased, the production of pottery might have become more centralized,
and occupants of peripheral blocks might have performed more specialized
tasks than did occupants of central blocks. The subsistence data for Yellow
Jacket Pueblo thus lend insights into many aspects of the lives and cultural
systems of the villagers and also raise many additional questions, especially
regarding changes in resource use through time, that offer intriguing
avenues for future research at the site.
