The direction of a glacier's movement is indicated by the orientation of its flow lines, which generally follow the slope of the underlying terrain. Additionally, features such as striations, which are scratches or grooves on the bedrock caused by the glacier's movement, can show the direction of flow. The position of moraines, which are accumulations of debris deposited by glaciers, also provides clues about the glacier's movement direction.
The direction of movement of a glacier is best indicated by the presence of striations on the underlying bedrock, the alignment of glacial erratics (rocks different from the surrounding bedrock), and the formation of drumlins (elongated hills of glacial sediment). Additionally, the shape of the glacier's terminus and the distribution of moraines can also provide clues about its movement direction.
Glaciers can move in any direction, including backwards, but typically they move in the direction of their accumulating mass (downhill). Factors such as changes in temperature, pressure, and topography can influence the direction of glacier movement.
A confined glacier is a glacier that is confined by topography. For example, a glacier that forms on a mountain. Continental glaciers, by contrast, are not affected. The glaciers on Antarctica and Greenland are continental glaciers. The glaciers at Glacier Bay National Park, or on a mountain are confined glaciers.
The gouging of bedrock by rock fragments dragged by glaciers results in the formation of grooves, scratches, and striations on the surface of the bedrock. These features, known as glacial striations, provide evidence of the direction and movement of past glaciers. These marks can also help geologists determine the extent and timing of glacial activity in an area.
The cryosphere, which includes glaciers, causes downhill movement of soils and water through processes like erosion, deposition, and transport. As glaciers move, they can pick up and carry sediments, shaping the landscape and contributing to the movement of water and materials downhill.

To determine the direction of past glacial movement on the Kingston Quadrangle, I analyzed glacial striations, which are scratches or grooves on bedrock caused by the movement of glaciers. Additionally, I examined the orientation of drumlins and moraines, which are landforms that indicate the flow direction of glacial ice. The alignment of these features consistently pointed toward the southeast, suggesting that the glaciers moved in that direction during their advance.

The movement of glaciers through the process of abrasion.The movement of glaciers.
"Static" means no movement or action indicated.
Continental glaciers move outwards in all directions from their center due to the force of gravity. The movement is influenced by the underlying topography and the weight of the ice mass.
Glacial striations are long, parallel scratches or grooves on bedrock caused by the movement of glaciers. As glaciers advance and retreat, they can pick up rocks and debris, which then act like sandpaper as the glacier moves, creating these striations on the underlying bedrock. Studying these features can provide information about the direction and extent of past glacial movement.
Glaciers acted as barriers, limiting movement for both people and animals. Glaciers could block pathways, forcing individuals to find alternate routes to travel. As glaciers retreated, they opened up new areas for habitation and migration.
