Estimated to weigh more than 67 tons, it remains where it landed less than 80,000 years ago, according to radioactive dating. The meteorite is now surrounded by a tiered viewing area. The story of how early cultures used metal from meteorites appears in the June 2023 magazine and is available to read in the link in bio. Follow @paoloverzone for more images and stories.」7月7日 4時00分
