CANADA: Parks Canada archaeologists have, for several years now, been searching for evidence of Sir John Franklin's doomed 1840s expedition to traverse the Northwest Passage, including the remains of his ships, HMS Erebus and Terror. Another season has passed without sign of the ships, but on land, archaeologists have continued to find artifacts. At a previously excavated site on Erebus Bay, where the expedition crew was stranded and around 20 of them died, researchers found more pieces of human bone, buttons, scraps of cloth, and a bone-handled toothbrush. —Samir S.
