A trim line, also written as trimline, is a clear line on the side of a valley formed by a glacier. The line marks the most recent highest extent of the glacier. The line may be visible due to changes in color to the rock or to changes in vegetation on either side of the line.

The term "trim line" is also used for similar looking phenomena caused by floods, volcanic activity, or tsunamis. (Full article...)

A cordillera is an extensive chain and/or network system of mountain ranges, such as those in the west coast of the Americas. The term is borrowed from Spanish, where the word comes from cordilla, a diminutive of cuerda ('rope').

The term is most commonly used in physical geography and is particularly applied to the various large mountain systems of the American Cordillera, such as the Andes of South America, and less frequently to other mountain ranges in the "ridge" that rims the Pacific Ocean. In Colombia and Venezuela, cordilleras are named according to their position: Cordillera Occidental, Central, and Oriental. Various local names are used for the cordilleras in Ecuador, Peru, Bolivia, Chile and Argentina. (Full article...)

A belayer in Red Rocks, Nevada

Belaying is a variety of techniques climbers use to create friction within a climbing system, particularly on a climbing rope, so that a falling climber does not fall very far. A climbing partner typically applies tension at the other end of the rope whenever the climber is not moving, and removes the tension from the rope whenever the climber needs more rope to continue climbing.

The term "belay" also means the place where the belayer is anchored; this is typically the ground or a ledge, but may be a hanging belay, where the belayer themself is suspended from an anchor in the rock. (Full article...)
