BASE jumping in the context of Acronym

In geography and geology, a cliff or rock face is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs.

An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers.

Wingsuit flying (or wingsuiting) is the sport of skydiving using a webbing-sleeved jumpsuit called a wingsuit to add webbed area to the diver's body and generate increased lift, which allows extended air time by gliding flight rather than just free falling. The modern wingsuit, first developed in the late 1990s, uses a pair of fabric membranes stretched flat between the arms and flanks/thighs to imitate an airfoil, and often also between the legs to function as a tail and allow some aerial steering.

Like all skydiving disciplines, a wingsuit flight almost always ends by deploying a parachute, and so a wingsuit can be flown from any point that provides sufficient altitude for flight and parachute deployment – a drop aircraft, or BASE-jump exit point such as a tall cliff or mountain top. The wingsuit flier wears parachuting equipment specially designed for skydiving or BASE jumping. While the parachute flight is normal, the canopy pilot must unzip arm wings (after deployment) to be able to reach the steering parachute toggles and control the descent path.

Preikestolen or Prekestolen (English: 'The Pulpit Rock', 'Pulpit', or 'Preacher's Chair') is a tourist attraction in the municipality of Strand in Rogaland county, Norway. Preikestolen is a steep cliff which rises 604 metres (1,982 ft) above Lysefjorden. Atop the cliff, there is an almost flat top of approximately 25 by 25 metres (82 ft × 82 ft). Preikestolen is located near the western part of the fjord, and on its north side.

Tourism at the site has been increasing in the early 21st century, with 300,000 visitors in 2024, making it one of the most-visited natural tourist attractions in Norway. BASE jumpers often leap from the cliff. Due to its increased popularity, the most used path to the site (a 3.8-kilometre (2.4 mi) long hike) was improved by Nepalese Sherpas in 2013.
