Title: Glacier National Park, Montana, presents a landscape carved by glaciers.
Caption: St. Mary Lake occupies a glacially eroded valley (glacial trough) and exists because of glacial deposits that act as a dam. The sharp ridges on the left (arêtes) and the pointed peak in the background (a horn) were also sculptured by glacial ice. (Copyright ©; by Carr Clifton. All rights reserved.)

Title: The only present-day continental ice sheets are those covering Greenland and Antarctica.
Caption: Their combined areas represent almost 10 percent of Earth¹s land area. Greenland¹s ice sheet occupies 1.7 million square kilometers, or about 80 percent of the island. The area of the Antarctic Ice Sheet is almost 14 million square kilometers. Ice shelves occupy an additional 1.4 million square kilometers adjacent to the Antarctic Ice Sheet.

Title: Iceland ice cap.
Caption: The ice cap in this satellite image is the Vantnajükull in southeastern Iceland (jükull means ³ice cap² in Danish). In 1996 the Grimsvötn Volcano erupted beneath the ice cap, producing large quantities of melted glacial water that created floods. (Landsat image from NASA)

Title: Malaspina glacier in southeastern Alaska is considered a classic example of a piedmont glacier.
Caption: Piedmont glaciers occur where valley glaciers exit a mountain range onto broad lowlands, are no longer laterally confined, and spread to become wide lobes. Malaspina Glacier is actually a compound glacier, formed by the merger of several valley glaciers, the most prominent of which seen here are Agassiz Glacier (left) and Seward Glacier (right). In total, Malaspina Glacier is up to 65 kilometers (40 miles) wide and extends up to 45 kilometers (28 miles) from the mountain front nearly to the sea. This perspective view looking north covers an area about 55 kilometers X 55 kilometers (34 miles X 34 miles). It was created from a Landsat satellite image and an elevation model generated by the Shuttle Radar Topography Mission (SRTM). Such images are excellent tools for mapping the geographic extent of glaciers and for determining whether such glaciers are thinning or thickening. (Image from NASA/JPL)

Title: North America's changing coastline.
Caption: This map of a portion of North America shows the present-day coastline compared to the coastline that existed during the last ice age (18,000 years ago) and the coastline that would exist if present ice sheets on Greenland and Antarctica melted.
