Stonehenge
Ritual village found
near famed rock site
Excavations in southern England of a village
dating to 4,600 years ago are transforming
archaeologists’ notions about the function
of nearby Stonehenge, the legendary set of
massive stones that people positioned on
Salisbury Plain around the same time.
Researchers led by Michael Parker
Pearson of the University of Sheffield in
England suspect that the same community
built both the village and Stonehenge as
parts of a religious complex devoted to the
dead. “We think we’re looking at a village
that was occupied by the builders of Stonehenge,” Parker Pearson says.
After massive feasts in town, villagers
transported bodies about 2 miles up the
River Avon to Stonehenge, where some were
interred after cremation, according to Parker
Pearson. The huge stones memorialized the
villagers’ deceased relatives, he asserts.
Parker Pearson and Julian Thomas of
the University of Manchester in England
described the new findings Jan. 30 during
a teleconference held by one of their funding organizations, the National Geographic
Society in Washington, D.C.
Many investigators have viewed Stonehenge as an isolated site used for religious
or astronomical purposes.

Parker Pearson’s team focused on a location called Durrington Walls. There, other
researchers had detected magnetic traces of
dozens of hearths typical of dwellings. Durrington Walls is a large henge, an enclosure
surrounded by an earthen bank and ditch.
That henge was last investigated in 1967.
The new project began in 2003 and will
run through 2010. Last September, Parker
Pearson and his coworkers uncovered
remains of eight houses at the site. Each
house measured about 16 square feet and
had a central fireplace set in a clay floor.
Postholes and slots in the floors once
anchored wooden furniture. Debris, including huge numbers of animal bones and

cooking implements strewn across the
floors, represents the remains of ancient
feasts, Parker Pearson says.
Radiocarbon dates for the houses overlap with previous age estimates for cremated remains discovered at Stonehenge.
The Durrington Walls houses bordered
a stone road, 90 feet wide and 560 feet long,
found in 2005 and further excavated last
year. The road runs from the remains of a
huge ceremonial circle of timbers to the
river. Two miles upstream, a comparable
road stretches from the river to Stonehenge.
Thomas excavated two Durrington Walls
structures on a terrace and surrounded by
wooden fences and ditches within the henge.
He suggests that these structures and at least
three others nearby served either as shrines
or as houses for community leaders.
The pair of roads at Stonehenge and Durrington Walls illuminates the complementary relationship between the sites, Parker
Pearson holds. For instance, Stonehenge’s
thoroughfare, discovered in the 18th century,
aligns with the midsummer-solstice sunrise,
while the Durrington Walls road lines up
with the midsummer-solstice sunset. Similarly, a set of three giant stones at Stonehenge
frames the midwinter-solstice sunset, while
the Durrington Walls timber circle aligns
with the midwinter-solstice sunrise.
Parker Pearson says that villagers appear
to have used Durrington Walls as a place
for periodic celebrations of life—held
before they moved their dead up the river
to the afterlife via cremation at Stonehenge,
a symbol of permanence.
Archaeologist Caroline Malone of the
University of Cambridge in England calls
the new findings “extremely exciting.” She
notes that to confirm their theory, the
researchers need to find more evidence of
graves and funeral activities in the Durrington Walls vicinity. —B. BOWER

Hurricane’s legacy
includes arsenic
Within the construction debris strewn
across the Gulf Coast by Hurricane Katrina is a disturbing amount of arsenic,
according to a new study. The tainted rubble, as it is currently managed, might contaminate groundwater, the researchers say.
Before 2004, chromated copper arsenate
(CCA) was the preservative most commonly
used to prevent pest infestation of construction wood. Because of arsenic’s toxicity, the Environmental Protection Agency
has since banned use of the chemical for
residential projects (SN: 1/31/04, p. 74).
However, many old utility poles, decks, and
fences contain CCA-treated wood.
During March 2006, Helena M.
Solo-Gabriele, an environmental engineer
at the University of Miami in Coral Gables,
Fla., and her colleagues surveyed debris in
New Orleans. They used a handheld
X-ray–fluorescence spectroscopy unit to
determine the concentration of arsenic
within 225 pieces of lumber from seven sites.
Of that sample, 52 pieces contained
arsenic, with a mean concentration of
1.24 grams per kilogram of wood.
Hurricane Katrina generated approximately 72 million cubic meters of debris,
