OTTAWA, Dec. 4 (Xinhua) -- A 13-kilogram meteorite has been discovered in western Canada after a rare meteorite shower fell across the country's western provinces last month, spraying thousands of rocks.

    An amateur meteorite hunter told reporters Thursday he found the huge rock about five kilometers from the pond where 10 such space rock fragments were found last week.

    University of Calgary Professor Alan Hildebrand found these rocks near the town of Lloyd minster in Alberta province on Nov. 27.

    They said they believed more fragments were strewn across a 20-square-kilometer area. Dozens more have been found after that, but none of them is bigger than one kilogram.

    An American meteorite collector has promised 10,000 U.S. dollars to the first person who found a kilogram-sized fragment.

    The meteorite shower took place on Nov. 20, when thousands of audience across Canada's three prairie provinces witnessed the spectacle.

    Canada's largest meteorite shower took in Alberta province, when more than 700 fragments were recovered in 1960.
