entstân

entstân is a term primarily used in the context of mountaineering and climbing to describe a specific type of rock formation. It refers to a rock face that has been significantly shaped by glacial erosion, resulting in a distinct, often rounded or U-shaped, profile. These formations are characterized by smooth, polished surfaces and steep, sometimes overhanging, sections where ice has scoured away the rock. The term is particularly prevalent in discussions of alpine environments where the effects of past glaciation are evident.

The formation of entstân is a slow process, occurring over thousands of years. As glaciers move, they carry debris, such as rocks and sand, which act like sandpaper, grinding and sculpting the underlying bedrock. Meltwater can also contribute to erosion, widening cracks and dislodging rock. The resulting entstân can present unique challenges and opportunities for climbers, offering both challenging ascents on its smooth, exposed faces and easier routes along more eroded, less steep sections. Understanding the nature of entstân is important for assessing climbing routes and potential hazards.
