Mail rappel
You're referring to a "mail rappel"!
A mail rappel is a type of climbing technique used in canyoneering and rock climbing where a rope is used to descend a vertical or near-vertical surface, such as a canyon wall or a rock face. The term "rappel" comes from the French word "rappeler," which means "to recall" or "to pull back."
In a mail rappel, the climber attaches themselves to the rope and then descends down the face of the rock or canyon wall, using their feet and hands to control their movement. The rope is typically anchored at the top of the rappel route, and the climber uses a device called a rappel device or an ATC (air traffic control) to control the descent.
Mail rappels are often used in canyoneering to descend steep canyon walls or to access remote areas. They require a good understanding of climbing techniques, rope management, and safety protocols to ensure a safe and successful descent.
Some common types of mail rappels include:
- Single-rope rappel: This is the most common type of rappel, where the climber uses a single rope to descend.
- Double-rope rappel: This type of rappel uses two ropes, one for ascending and one for descending.
- Multi-rope rappel: This type of rappel uses multiple ropes, often used in complex or exposed rappels.
Overall, mail rappels are an essential skill for canyoneers and rock climbers, allowing them to access remote areas and experience the thrill of descending steep and challenging terrain.
