Archaeologists at Historic Jamestowne have ended their 2007 excavation season after months of exploring one of the pioneering English fort's most complex and significant architectural features.

First uncovered in mid-2006, the sinking, dark-stained patch of soil originally looked like a nearby well so richly packed with artifacts that it had required a summer of digging. But as archaeologists probed deeper, the feature expanded dramatically in size, revealing at least three successive cellar floor levels that dated to the earliest days of the settlement.
