A JOB REQUIRING a Ph.D. that has you out playing in dirt, up to your knees in black muck or ducking bat droppings in old caves ought to go begging. Yet archeology hooks hordes of otherwise normal Washingtonians, luring them into mosquito- and poison-ivy-infested fields and lots, down to old (and new) river beds and even underwater, seeking the ancestral trash that helps us puzzle out our history.

And they're looking for volunteers.

Local archeologists -- many hired to comb construction sites before the bulldozers -- flesh out their crews with volunteer grunts. Teens, singles, weekend workers and senior citizens go out regularly on digs, put in hours with the artifacts at the labs, walk their fingers through county and city records and help write reports.

What hooks them all is an area profoundly rich in archeological evidence; Washington has been the Far East (for native Americans) and Wild West (for 17th-century Europeans), as well as the crucible of our deadliest war. With archeologists from a half-dozen local jurisdictions, plus the local universities, the National Park Service and the Maryland Geological Survey digging for our roots among Mother Nature's, chances are good that you'll find someone investigating the point in the past that interests you most.

For some, like Ray Arebaugh, volunteering can lead to a career. "It started with a trip I made to Gettysburg when I was 12 or 13, which really impressed me," he says. "I thought then that I wanted to be an historian. But now that I've worked on this end, I want to be an archeologist." Arebaugh has put in thousands of hours with the Fairfax Archeology office, and is working toward a degree in the discipline at George Mason University.

Not everyone will go that far, of course, though the archeologists get lots of volunteers thinking they might like to. So first, let's debunk the myths: Archeology is to Indiana Jones as hang-gliding is to growing your own wings. If you go on digs (professionals prefer "excavations"), you're more likely to come away with rashes and bug bites than treasure. The hours are long, the work is dirty, and for reasons that have more to do with the academic schedule than common sense, archeologists dig during the hottest and muggiest months.

And people love it. So much so that the Alexandria Archeology Lab doesn't want us to publish their telephone number ("We've got 60 people on the waiting list already"); the National Park Service doesn't want us to tell where their sites are ("Terrible trouble with relic hunters," says NPS archeologist Steve Potter); and the barest mention of a new dig turns out two or three dozen folks, shovels in hand.

"But the chaff gets separated from the wheat after those first hours of sweat, chiggers and blood blisters," Potter says, with a smile. "So the next week, they don't show." Any given dig in the Washington area eventually boils down to 10 to 20 dedicated volunteers -- "usually self-motivated or well- educated people, the type who support WETA and get Smithsonian and National Geographic," says Potter. They work trowel-to-trowel with the archeologists, digging up, to use Potter's term, neat stuff.

Like a Clovis point arrowhead, as in Clovis, New Mexico. That was found by an amateur just outside of Front Royal, where the professionals quickly uncovered evidence of the oldest semi-permanent settlement in all of North America. We're talking 12,000 years ago, when Indians, attracted by the site's stones, water and bog (the better for hunting what may have been woolly mammoths), set up a lodge large enough for perhaps 20 people, built of saplings covered with animal skins.

Archeologists and volunteers at the Thunderbird Museum and Archeological Park have recreated the lodge, but are still trying to cover it with deerskins brought in by hunters. "Animals in those days were much larger," says a spokesman, "so it took far fewer skins to cover, we think."

Then there are the Civil War relics Katie Parker is finding at Manassas Battlefield Park, where she and the volunteers are looking for evidence of the Battle of Groveton, which took place on the eve of Second Manassas (Bull Run). Parker's trying to map out the exact geography of the place at the time of the conflict, locating original buildings and the road where two of the great units of the war -- the Stonewall Brigade and the Iron Brigade -- had at each other.

Historical archeology covers a lot of ground. Baltimore's Center for Urban Archeology, a fairly new group, is looking at the city's 19th-century, blue-collar past to see how the common man ate, drank and made merry. To this end they've excavated an old brewery (and found evidence that the owner lived on the premises), and dug into an old waterfront (finding all manner of junk).

The goo the artifacts were buried in at the waterfront acted as a kind of "horrible" preserver, says conservator Helen Cox. The Center stuck the things they removed in a higher-tech preservation agent ("We shoved them in the refrigerator, see?" says chief archeologist Elizabeth Comer) until the conservator could get to them.

"Look," says Comer, taking a shoe sole from the shelf, "you can even see the imprint of his foot. And aren't these funny pointed toes?" she asks.

Getting involved in most of these programs takes only a phone call; the archeology offices will direct you to where the excavation crews meet. "Most people say they want to dig," says Alexandria's Steve Shepherd, "but they may not like being out all day in the hot sun as much as other parts of archeology."

The groups we contacted also need researchers to sort through court documents, census records, journals, diaries, business directories and whatever to find any record of the site. "It's like a mystery sometimes," Shepherd says. "You look in all the usual places and then think, the owners must have left some record of themselves, where else can I look? Some people really enjoy this sort of sleuthing."

Then there are lab volunteers like J. Rosalie M. Bond, a senior citizen who comes weekly to Baltimore's Center to sort through the boxes and boxes of artifacts they've dredged up. Bond washes them, gives each a number, and compares them to similar pieces to see what they might be.

"We have senior citizens who come to work in the lab who are just wonderful," says Fairfax archeologist Sue Henry. "They end up knowing the artifacts better than we do."

Serious volunteers may want to go to a field school, where they learn basic excavation techniques, site survey, lab procedures, even artifact photography and computing. Most are one- to two-week, intensive learning experiences, but Thunderbird and the Center for Urban Archeology have some weekend schools set up that would be fun for working stiffs.

Most of the schools are given for college credit, but several also take high school students. "I just wrote recommendations for one young woman who's been coming out here to volunteer," says Potter. "She's going to college to major in archeology."

Then there's underwater archeology, perhaps the most glamorous end of the field; certainly the closest to treasure hunting. You need to be certified in scuba diving before they'll let you on the boat, though. And even reputable archeologists are liable to be pretty private and closemouthed about what they're looking for.

The Maryland Geological Survey is doing an underwater survey of the Chesapeake Bay this summer, looking for potential sites, including prehistoric ones. That might turn up all kinds of goodies, if you're interested.

At least you'll avoid the poison ivy. SITES TO SEE:
