#throwbackthursday 1999 and our magnificent expedition into the Popigai meteorite crater in the Siberian Arctic. We were the first ever non-Russian team allowed to visit the site. The crater is so vast and so remote, the only way in and out was by Russian ex-military Mi8 helicopter. At this site we were exploring a ghost town, once inhabited by workers who mined impact diamonds from the crater.
