Lama (geology)

In geology, a lama refers to a steep, often narrow, gorge or ravine formed by fluvial erosion, particularly in mountainous regions. The term is used primarily in specific geographic locales, notably in parts of the Pyrenees mountains, and is not a universally recognized or standardized geological term. While similar to other terms like "gully," "ravine," or "canyon," the use of "lama" often implies a smaller scale and localized formation context. The formation of a lama involves the downcutting of a stream or river through resistant rock, resulting in steep sides and a confined channel. The exact geomorphological processes and geological context may vary depending on the specific region where the term is applied.
