A glacial terminus Satellite view of changing glacier termini in the Bhutan-Himalaya, showing glacial lakes formed by the retreating termini on the surface of the debris-covered glaciers over the last several decades. A glacier terminus, toe, or snout, is the end of a glacier at any given point in time.
Sulphur Glacier is located in Shoshone National Forest, in the U.S. state of Wyoming on the east of the Sunlight Peak in the Absaroka Range. [2] The glacier sits at an elevation of between 11,000 and 10,400 ft (3,400 and 3,200 m).
The Aruküla Rock (Estonian: Aruküla hiidrahn) is a glacial erratic on the field of Aruküla, situated in Harju County, Estonia. It has a circumference of 35.2 m , height of 6.2 m . 59°12′50″N 25°24′18″E / 59.2140°N 25.4049°E / 59.2140; 25
The southernmost glacier in this list, near the limit of the Yelm lobe of the Vashon Glacier in the Rainier (city) area. [29. 15 feet (4.6 m) Thurston Lake Stevens Monster near Lake Stevens. 34 by 78 feet (10 m × 24 m) and 210 feet (64 m) in circumference.
During the Last Glacial Maximum, much of the world was cold, dry, and inhospitable, with frequent storms and a dust-laden atmosphere. The dustiness of the atmosphere is a prominent feature in ice cores; dust levels were as much as 20 to 25 times greater than they are in the present.
A 1992 to 1998 observation of the Chacaltaya Glacier in Bolivia and Antizana Glacier in Ecuador indicate that between 0.6 m (2.0 ft) and 1.9 m (6.2 ft) of ice was lost per year on each glacier. Figures for Chacaltaya show a loss of 67% of its volume and 40% of its thickness over the same period.
Glacial striations are usually multiple, straight, and parallel, representing the movement of the glacier using rock fragments and sand grains, embedded in the base of the glacier, as cutting tools. Large amounts of coarse gravel and boulders carried along underneath the glacier provide the abrasive power to cut trough-like glacial grooves.
The recent retreat of a marginal outlet glacier of Hofsjökull in Iceland [21] exposed a drumlin field with more than 50 drumlins ranging from 90 to 320 m (300–1,050 ft) in length, 30 to 105 m (100–340 ft) in width, and 5 to 10 m (16–33 ft) in height.
