I'm sorry, but as a text-based AI, I am unable to draw images. However, I can provide you with a description of the ridge tier and its components, along with their names and functions.
The ridge tier refers to the uppermost part of a mountain range or ridge. It typically consists of various components that contribute to the overall structure and function of the ridge. Here are some common components found in a ridge tier:
1. Summit: The highest point of the ridge, often referred to as the peak or summit. It is the culmination of the ridge and offers panoramic views of the surrounding landscape.
2. Crest: The ridge's highest point along its length, forming a continuous line or crest. It represents the backbone of the ridge and provides stability to the overall structure.
3. Saddle: A low point or depression between two higher points along the ridge. It resembles a saddle shape and often serves as a pass or route for hikers or climbers to traverse from one side of the ridge to the other.
4. Spur: A ridge that extends laterally from the main ridge, resembling a spur or projection. Spurs often provide additional ridgeline for exploration and can offer unique viewpoints.
5. Col: A low point or depression between two adjacent peaks or ridges. It is similar to a saddle but typically deeper and wider. Cols can act as natural barriers or passes between different valleys or drainage systems.
6. Knife-edge: A narrow and sharp ridge section with steep drops on both sides. It is characterized by its thin and exposed nature, often requiring careful navigation. Knife-edges can add excitement and challenge to ridge traverses.
7. Gendarme: A pinnacle or tower-like feature along the ridge. Gendarmes are typically steep and jagged, adding aesthetic appeal to the ridge and sometimes requiring technical climbing skills to ascend or bypass.
8. Notch: A narrow gap or cleft in the ridge, often formed by erosion or geological processes. Notches can provide access to adjacent valleys or serve as landmarks for navigation.
These are just a few examples of components that can be found in a ridge tier. The specific names and functions may vary depending on the geographical location and characteristics of the ridge.
