The archaeological dig at Pig Point, Maryland (USA), has continued to yield incredible artefacts and other evidence of human activity since its initial discovery in 2009. Findings include evidence of Algonquin wigwams (shelters), projectile points, ancient pottery and other artefacts dating back thousands of years further than anyone expected.
     Dr Al Luckenbach, county archaeologist and leader of the dig, said they have dug down to prehistoric bedrock in a few locations and have found artefacts nearly the entire way down. "This is actually seven feet (2m) of one continuous occupation after another." The excavations have revealed numerous broken pieces of decorative necklaces. "What we're finding is that after they're broken they're marking little designs on them and then tossing them," said Luckenbach. "One theory... Would say this thing had power to them ...And when it's broken you can't just throw it away."
     A projectile point made from Ohio stone has Luckenbach theorising that the mound-building Hopewell tribe of that area may have traded with the Algonquin tribes that inhabited this site just a few hundred years ago - a relationship that was not previously thought to exist.
     Projectile points are a common discovery. "Triangle points are typically considered to be arrowheads but we're finding them way farther down than the arrow was supposed to be invented," said archaeologist Jessie Grow. "Either they had the arrow much earlier than we originally thought, or they were using triangle points for spear tips as well."
