The movement of these continental glaciers created many now-familiar glacial landforms. As the glaciers were expanded, due to their accumulating weight of snow and ice, they crushed and redistributed surface rocks, creating erosional landforms such as striations , cirques , and hanging valleys .
The critical speed is what determines the speed limit for vehicles traveling on ice roads. That limit can be as low as 10 to 35 km/h (6 to 22 mph). [3] [4] Dynamic loading of the ice cover may also dictate a minimum distance between vehicles. [4] [2] The effects of dynamic loading on a floating ice sheet has been investigated via field testing.
The Portage Glacier Highway, or Portage Glacier Road, is a highway located in the U.S. state of Alaska. The highway is made up of a series of roads, bridges, and tunnels that connect the Portage Glacier area of the Chugach National Forest and the city of Whittier to the Seward Highway .
Camas Creek Cutoff Road at the entrance To Glacier National Park. The Camas Creek Cutoff Road (also known as Camas Road) is an 11.7 mile long road located in Glacier National Park. The road connects the Going-To-The-Sun Road to the east with the North Fork Road to the west. The road is not highly trafficked and does not access many major park ...
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 South Pole Traverse, also called the South Pole Overland Traverse (SPoT), [2] or McMurdo–South Pole Highway [3] is an approximately 995-mile-long (1,601 km) flagged route over compacted snow and ice [4] in Antarctica that links McMurdo Station on the coast to the Amundsen–Scott South Pole Station, both operated by the National Science Foundation of the United States.

A glacier stream is a channelized area that is formed by a glacier in which liquid water accumulates and flows. [1] Glacial streams are also commonly referred to as "glacier stream" or/and "glacial meltwater stream". The movement of the water is influenced and directed by gravity and the melting of ice. [1]
The glacier's speed of retreat at the terminus reached a maximum of nearly 30 meters (98 ft) per day in 2001, when it was discharging icebergs at approximately 7 cubic kilometers (1.7 cu mi) per year; the glacier has subsequently slowed down, resulting in an increase in retreat rate.
