WATSON BRAKE is an archaeological site in Ouachita Parish, Louisiana
, from the Archaic period . Dated to about 5400 years ago (approx.
Watson Brake is considered the oldest mound complex in
North America . It is older than the Egyptian pyramids and
The arrangement of human-made mounds was constructed over centuries
by members of a hunter-gatherer society, and is located in the
floodplain of the
Ouachita River , near present-day Monroe in northern
United States .
Watson Brake consists of an oval formation
of eleven earthwork mounds from three to 25 feet (7.6 m) in height,
connected by ridges to form an oval nearly 900 feet (270 m) across.
Watson Brake is dated to 1,900 years before the better-known Poverty
Point in northern Louisiana, begun about 1500 BCE and previously
thought to be the earliest mound site in North America. In the
Americas, mound building started at an early date.
The discovery and dating of
Watson Brake as a Middle Archaic site
demonstrate that the pre-agricultural, pre-ceramic, indigenous
cultures within the territory of the present-day
United States were
much more complex than previously thought. While primarily
hunter-gatherers, they planned and organized large work forces over
centuries to accomplish the complex mound and ridge constructions.
Monumental constructions have marked the rise of social complexity
world-wide. The earthen mounds of Eastern
North America are linked to
mankind's monument tradition.

DISCOVERY AND DATING
Schematic plan of the
Watson Brake Site
In the early 1980s, Reca Bamburg Jones, a local resident, brought
this site to the attention of professional archaeologists. By 1981,
after logging had revealed more of the site, Jones identified the
pattern of eleven mounds connected by ridges, a complex that was 280
yards across. In 1983, Jones and John Belmont published the site in a
survey of pre-history in the
Ouachita River Valley. Around this time
Joe Saunders, then regional archaeologist for the state, was shown the
The site had been privately controlled since the 1950s. Approximately
half the site is still owned by several family members, who have
allowed archaeological excavations and associated work. Recognizing
the site's significance, in 1996 The Archaeological Conservancy
purchased half the site and later sold it to the state for
Since the 1990s, radiocarbon dating by a team from Northeast
Louisiana University established the great antiquity of the site. The
team of Joe W. Saunders et al. published a paper in Science in 1997
that established the age of the mound complex.
The analysis of 27 radiocarbon dates indicates that the site was
initially occupied around 4000 BCE during the Middle Archaic period .
Mound construction began at approximately 3500 BCE, and continued for
approximately 500 years. During that time period, the mounds were
enlarged in several stages. Excavations indicate that there was
sufficient time between building episodes for midden deposits of
residents to accumulate on top of the mounds and ridges. In addition,
teams from the University of Texas at Austin and the University of
Washington dated the site by using sand grains and organic acids in
Evidence of the middens indicate that
Watson Brake may have been used
as a "base by mobile hunter-gatherers from summer through fall."
Saunders and his team suggest that the building episodes at Watson
Brake coincide with periods of unpredictable rainfall caused by El
Nino-Southern Oscillation events. They may represent "a communal
response to new stresses of droughts and flooding that created a
suddenly more unpredictable food base."
Midden remains showed the
population relied on fish, shellfish, and riverine animals,
supplemented by local annuals: goosefoot (Chenopodium berlandieri),
knotweed (Polygonum spp.), and possibly marshelder (Iva annua). Over
time, the people consumed more terrestrial animals, such as deer,
turkey, raccoon, opossum, squirrel, and rabbits, which was likely
related to changing habitat and waterway conditions. The site appears
to have been abandoned around 2800 BCE. This may have been caused by
a "decline in the main channel, gravel/sand shoal habitats, backwater
swamps, and small-stream habitats" near the site.
Together with other Middle Archaic sites in
Louisiana and Florida,
Watson Brake shows the development of complex societies among
hunter-gatherer peoples. They occupied the site only on a seasonal
basis, but were capable of planning and organizing complex monumental
construction over a period of several hundred years.
In contrast to Poverty Point, where its residents made projectile
points with materials traded from distant locations, including
Wisconsin and Tennessee, the artifacts of
Watson Brake show local
materials and production. The projectile points are Middle to Late
Archaic in age, and were produced more casually than those at Poverty
Point. The people heated local gravel for cooking stones to steam some
of their food. They created and fired earthenware items in a variety
of shapes, but researchers have not yet determined their functions.
OWNERSHIP AND MANAGEMENT
Eight members of the Gentry family have owned most of the site since
the 1950s. One member declines to sell property to the state, so the
site is not available for public viewing. The family have allowed
archaeologists to do research on site.
