It worries scientists because it sits on a bed that slopes back towards the land - a geometry that tends to assist thinning and withdrawal. For instance, if it's known how much ice is entering a narrow valley and how fast it's moving - the volume of that ice can be worked out, giving an insight into the depth and roughness of the hidden valley floor. At its thickest point the ice sheet is 4,776 meters deep. The Park Service's A-Star B3 helicopter, with Mount Rainier National Park . Mapping where crevasses appear is equivalent to mapping where the ice tensional stresses are highest. Their orientation may be in any direction with respect to the glacier flow. She is also the first woman to ever climb both Mount Everest and Mount Lhotse in a single 24-hour period. The blue color is due to absorption of light in the red portion of the visible spectrum by molecules of water. This ice-filled canyon reaches 3.5km (11,500ft) below sea level.

To detect subtle crevasses, you need to look for faint linear offsets in the snow, and, if you find one, probe it with an ice axe or a pole to see how thin and wide it is. What would Antarctica be like without ice? If East Antarctica is threatened, it's not from the Ross Sea," Dr Morlighem said. If a glacier has only a thin layer of snow, or no snow, you can usually see these shadows. They can reach up to 10 meters wide and are usually found in transverse crevasses on ice sheets and flat areas of a glacier. The deepest crevasses may exceed 30 m. Theoretically, the weight of the ice limits crevasse depth to about 30 m. Below that there is typically enough compressive force in the ice to prevent cracks from opening. Place one on your tongue and feel it melt away. The hole is formed when huge pieces of ice separate from one another leaving a space between them. Icebergs fall.
