In navigation, what is a finger typically referred to in geographical terms?

In geographical terms, a finger is commonly used to describe a narrow projection of land that extends outward. This term can apply to land formations that resemble a finger in shape, often jutting out from a larger landmass into a body of water or into surrounding terrain. This projection can have significant implications for navigation, as it often defines boundaries, shorelines, and can be critical for maritime passage.

While other geographical features like upland areas, prominent ridges, and deep valleys play essential roles in the topography of a region, they do not specifically capture the essence of what a "finger" represents in navigation. The focus on the narrowness and extension is what makes the term distinctly applicable to certain landforms. This concept is vital for sailors and navigators who must be aware of such features in order to safely navigate waterways and understand the geography of the land they are traversing.
