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

later on there was a little bit of controversy because when she took up with sidney llewellyn in theearly mid 1950s. he worked with her to encourage her to work on to change grip. that also explains the rather kind of low dip in form that she took right between 1951. and when she finally starts clawing back. by 1956 was a tough adjustment. she really she wasn't into the visual right. so fred johnson noted that she wasn't always the most studious player in terms of giving her, say, a book or something to study the moves. but she was really quite strong when it came to watching what other folks were. and she was known for those groundstrokes for her just terrific forehand. she was very proud of her serve. she loved the overhead smash and i don't know if they called it trash talk back then, but the story goes that a reporter said maybe during a q&a question on the strength of her backhand, perhaps he said it was weak. she found him after the press of that, and she told him that her backhand was doing just fine. she loved practicing with the male players and just again, back to the work
