Program Overview

|
NOVA follows glaciologists into the underworld of Mont Blanc, where they search for internal lakes.
The program:
revisits the 1892 disaster in which a hidden lake burst forth from a
glacier on the French side of Mont Blanc, killing more than 100 people. features glaciologist Luc Moreau, who explores a "water well" (an ice
shaft formed by meltwater) to try to predict future flood events. explains how a glacier forms. relates some of the problems of being in an unstable environment, where
water is always changing from liquid to solid and back again. follows Moreau into his lab inside Mont Blanc's Argentiere Glacier, where
he measures the movement of the glacier and tries to determine where the water
flows. introduces Carsten Peter, an ice adventurer who explores and photographs
ice caves. features Peter's dive into a water well inside the Mer de Glace, the
largest glacier on Mont Blanc, and shows all the equipment needed to make a
dive at extremely cold temperatures and at high altitude. shows the methods Peter and Moreau use to try to determine whether there
are any interior lakes.
Taping Rights: Can be used up to one year after the program is taped off the air.
