A 1,100-year-old crater created by a meteorite the size of a big tree trunk has been discovered underneath thick growth (top) in western Canada, a November 2008 study said.

Scientists used a new crater-spotting imaging technique to "strip" away the vegetation and reveal the 120-foot (36-meter) wide circular impression (bottom).
