Evidence of Pre-Columbus Trade Found in Alaska House

Bronze artifacts discovered in a 1,000-year-old house in Alaska suggest trade was occurring between East Asia and the New World centuries before the voyages of Columbus.

Archaeologists found the artifacts at the "Rising Whale" site at Cape Espenberg.

"When you're looking at the site from a little ways away, it looks like a bowhead [whale] coming to the surface," said Owen Mason, a research associate at the University of Colorado, who is part of a team excavating the site.
