  Prehistoric Disaster: An Alpine Pompeii from the Stone Age

Prehistoric Disaster An Alpine Pompeii from the Stone Age

By Matthias Schulz

Part 2: A Possibility of Mummies?

As effective as the bartering network in this Stone Age European Union was, agriculture and raising livestock were not well developed. In the early lakeside villages, milk and cheese were rare, hay was unknown as animal feed and the settlers had not yet discovered the benefits of using sheep's wool for clothing. The fields were relatively unproductive. The lake dwellers preferred fishing and hunting for deer -- or roasting dogs for supper.

The villages were filled with garbage and waste, and the residents relieved themselves directly from the walkway into the lake. Washing dishes was apparently unpopular. Archeologists have found pots containing the encrusted remains of food and fish bones baked into the clay.

The ancient population reached Mondsee Lake around 3600 B.C. They probably came from the Balkans, as the circular designs on their pottery suggest. They felled oaks and willows with stone hatchets, using the lumber to make the first thresholds for their new houses along the swampy lakeshore.

Despite its drawbacks, the location was an astute choice. A small creek next to the village flowed to the nearby Attersee Lake, providing natural drainage for the villagers' foul-smelling sewage and fecal matter. Steep hills on both sides created a funnel-like effect, so that there was constantly a breeze in the settlement. This helped fire the copper furnaces, which required operating temperatures of about 1,100 degrees Celsius (2,012 degrees Fahrenheit).

Enormous Tectonic Forces

But there was one thing the settlers did not know: The Mondsee Lake is at the interface between enormous tectonic forces. "The jagged Alpine limestone mountains of the Schafberg region of Tyrol on the southern shore presses against the soft rock of the Flysch region on the opposite shore," Binsteiner explains. The cliffs are pushed up, millimeter-by-millimeter, becoming increasing steep, until they become top-heavy and eventually break off.

Although this only happens extremely rarely, the consequences can be devastating, as comparable landslides show. In 1958, for example, a jagged cliff wall fell into Lituya Bay, producing a 524 meter (1,720 foot) localized tsunami. In 1963, 260 million cubic meters (2.8 billion cubic feet) of rock crashed into the Vajont Reservoir in northern Italy, killing about 2,000 people.

Zürich geologist Flavio Anselmetti collects the evidence of such disasters. Using ultrasound, he scanned the bed of Lake Lucerne and located countless boulders caused by landslides and "sub-aquatic slides." "There was a serious tsunami here at around 1000 B.C.," he says, "and in 1806, a village of 500 inhabitants was destroyed on Lake Brienz."

Drill cores of the sediment provide the evidence of the landslide at Mondsee Lake. They show that the avalanche of rock plugged the lake's drainage system, causing the water level to rise rapidly by two to four meters (six to 13 feet).

But efforts to determine exactly when the event occurred have been less conclusive. "All we know so far is that the landslide happened sometime after the end of the first Ice Age, around 10,000 B.C.," says Anselmetti.

This is far from exact. It could very well be that the boulders came crashing into the lake when Mondsee Lake was still uninhabited.

Mummies?

Binsteiner, at least, has additional evidence to support his theory of an apocalypse brought on by a landslide. In 1872, the lake dwelling was discovered in shallow water and crudely dug up with long excavator shovels. More than 10,000 artifacts were uncovered. They are among the finest relics of the Neolithic Age.

The site was already remarkable for the weapons discovered there, including 595 stone hatchets, cudgels and studded battleaxes, 451 arrowheads along with a dozen hatchets and six daggers made of copper. In the Neolithic Age, these metal tools were such sought-after status symbols that they were even beyond the reach of many a tribal leader.

If it was so valuable, why was this costly arsenal left lying in the mud? "If the site had been abandoned peacefully, such treasures would never have been left behind," says Linz archeologist Ruprechtsberger.

The countless charred fruits found in the mud beneath the settlement are yet another sign that it came to an abrupt end. They include blackened, hard hazelnuts, ears of grain and even pieces of apples, all of them extremely well preserved, because they were quickly deprived of oxygen. Were they preserved by the wave of mud brought on by the tsunami?

Given the many clues, archeologists are anxious to come up with explanations soon. "We need a new, large excavation project at the site of the disaster," says Binsteiner. "Perhaps we will even find mummies there."
