What is Trekking?

What is Trekking? "Trekking is a form of walking, undertaken with the specific purpose of exploring and enjoying the scenery. It usually takes place on trails in areas of relatively unspoiled wilderness. Mountaineering is the sport, hobby or profession of walking, hiking, backpacking and climbing mountains. It is also sometimes known as alpinism, particularly in Europe. While it began as attempts to reach the highest point of unclimbed mountains, mountaineering has branched into specializations that address different aspects of the mountain and consists of three areas : rock-craft, snow-craft and skiing, depending on whether the route chosen is over rock, snow or ice. All require experience, athletic ability, and technical knowledge to maintain safety. Rope, cord and webbing Climbing ropes are typically of kern mantle construction, consisting of a core (kern) of long twisted fibres and an outer sheath (mantle) of woven coloured fibres. The core provides about 80% of the tensile strength, while the sheath is a durable layer that protects the core and gives the rope desirable handling characteristics.Ropes used for climbing can be divided into two classes: 1. dynamic ropes Dynamic ropes are designed to absorb the energy of a falling climber, and are usually used as Belaying ropes. When a climber falls, the rope stretches, reducing the maximum force experienced by the climber, his belayer, and his equipment. 2. Static ropes. Static ropes stretch much less, and are usually used in anchoring systems. They are also used for abseiling (rappelling) and as fixed ropes climbed with ascenders.

Modern webbing is often made from dyneema, which is usually stronger and lighter than nylon. While 12 mm dyneema slings have a tensile strength of around 22kN, a one-inch (25-mm) tubular climb-spec nylon webbing has a tensile strength of about 20 kN (4000 pounds) Some webbing is tubular or hollow core and is advantageous because rope can be placed inside of it, preventing damage to the sheath of a kernmantle rope if it hangs over a sharp edge. Webbing is inexpensive when compared with climbing rope.



When webbing is sewn together at the ends (using reinforced stitching), it becomes known as a sling or runner, and if you clip a carabiner to each end of the sling, you have a quick draw. Webbing has many uses such as extending the distance between protection and a tie-in point, an anchor extension or equalization, securely anchoring a belayer (typically when the climber is heavier than the belayer), creating makeshift harnesses, carrying equipment, and as a component of quickdraws. Webbing is usually tied (using a water knot). File:Water-knot-webbing-tight-ABOK-296.jpg
