👉 A hazeline is a narrow, winding path in a valley or mountain range. It is often used to describe a narrow and steep slope of land that can be difficult to navigate due to its steep incline. Hazelines are often associated with mountain ranges, which have steep cliffs and rugged terrain. They are also commonly found in the United States, where they are often seen on mountainous areas like the Sierra Nevada, which is known for its high peaks and narrow valleys.
