Water Gap

A water gap is a natural valley or pass where a river cuts through a mountain range or ridge, often remaining at a consistent level over time. It typically forms when a river maintains its course while the land around it uplifts due to tectonic activity, creating a narrow, low-lying corridor through the mountains. These gaps are important for transportation, offering natural routes through otherwise difficult terrain, and they reveal information about geological history and erosion processes shaping the landscape.
