The ridge separating two glacial valleys is known as an arête. These sharp, narrow ridges are formed by the erosive action of glaciers on either side, carving out the landscape over thousands of years. Arêtes are typically found in mountainous regions where glaciers have once flowed through. They are often characterized by steep, jagged cliffs on either side, creating a dramatic and awe-inspiring landscape. One of the most famous examples of an arête is the Knife Edge on Mount Katahdin in Maine. This narrow ridge provides a thrilling and challenging hike for experienced climbers, offering breathtaking views of the surrounding valleys. Arêtes play an important role in shaping the geography of glaciated regions, creating distinct features that are a testament to the power of ice and erosion. They are also important for understanding the history of glacial activity in an area, providing valuable insights into past climate conditions and geological processes.

This site offers detailed explanations and illustrations of how arêtes are formed, as well as examples of famous arêtes around the world. In conclusion, the ridge separating two glacial valleys is called an arête. These unique landforms are a testament to the power of glaciers and erosion, shaping the landscape in dramatic and beautiful ways. By studying arêtes, we can gain a better understanding of the forces that have shaped our planet over millions of years.
