How Archaeology Works

An Archaeologist's Work: Fieldwork and Excavation

It's easy to imagine the archaeologist in the field -- a modern-day adventurer discovering the mysteries of the past before whisking off to a new, even more fascinating site. The archaeological process, however, begins long before the spade hits the dirt. Every excavation involves years of study, scouting and planning.

Some archaeologists consider fieldwork the entire outdoor archaeological process, from scouting to digging. Others consider fieldwork the pre-dig activity and differentiate it from actual excavation. This preliminary work includes everything from consulting aerial photographs, old maps and physical references in literature, or even using high-tech methods like geophysical prospecting, a technique that measures electrical conductivity in soil.

This type of meticulous fieldwork prepares archaeologists for planned excavations. However, not all excavations are planned; there are also accidental excavations and rescue excavations. Some of the greatest archaeological finds are simply fortunate discoveries. In 1940, four French schoolboys found themselves in a chamber ornamented in Upper Paleolithic masterpieces. They had simply been exploring a tunnel exposed by an uprooted tree. In 1947, a Bedouin shepherd discovered the first Dead Sea Scrolls, the earliest copies of any Biblical books, while searching for a stray animal.

Sometimes, accidental finds become rescue excavations. Construction projects often unearth archeological sites that must be explored and recorded quickly so that business can continue. When a city has as many layers of history as Rome, archeological finds are inevitable; every request for a building permit -- all 13,000 annually -- requires an archaeological evaluation [source: National Geographic]. Sometimes such thoroughness can cripple a city. Rome struggles to meet the demands of its 2.8 million citizens while preserving its history [source: U.S. Department of State].

But because excavation inherently destroys a site, an archaeologist must record the placement of every artifact. This record ultimately becomes a primary source for other archeologists and historians to consult since the actual primary source -- the site itself -- no longer exists in its original form. The archaeologist also brings in experts from other disciplines like geology or metallurgy to help analyze the finds.
