the huge llewellyn glacier in canada is melting fast, exposing more of its secrets for researchers brooke stamper and mira dutschke to discover, using photogrammetry and ice lens measurements. as the 2013 field season on the icefield comes to a close, we make our way northeast and walk off the llewellyn glacier through a dangerous crevice field. >> we're winding our way through the crevices of the llewellyn glacier. everyone's making their way very carefully here because the glacier gets a little broken up, but it's a beautiful day, and it looks like we might make it all the way to lake atlin. >> we struggle down through this dusty and blowing newly uncovered ground where the vast llewellyn has melted and finally we make our way down this long valley to lake atlin. here we're picked up by a boat and start deciphering the data and working it into the scientific literature, where researchers around the world can use it to fine tune their climate change predictions. from the glaciological and arctic sciences institute on lake atlin, british columbia, this is jeffrey barbee reporting for link

llewellyn jones lives in wilson, north carolina. her basement was flooded when a nearby creek overran its banks. >> we had about four and a half feet of water in our driveway. it was over the hoods of both our cars. probably a good three feet in the house that turned our freezer over, washer, dryer. >> ifill: from there, the storm system pushed north, dumping as much as five inches of rain across parts of the mid-atlantic and into the northeast. >> ifill: for more on the flooding, we spoke a short time ago on the phone with ashton hayward, the mayor of pensacola, florida. welcome, mayor. as of 6:00 p.m. eastern time, we're hearing that there's been one reported death so far. how extensive would you say the damage is in pensacola? >> well, gwen, you are getting total up in dollars close to the $100 million mark or more. we've been rescued people late to the evening last night and obviously to the early morning. flooding that we're not used to, gwen. as you know we're used to the hurricanes but not the flooding. it's kind of an anomal
