2. Anchor (climbing) - Wikipedia

   en.wikipedia.org/wiki/Anchor_(climbing)

   In rock climbing, an anchor can be any device or method for attaching a climber, rope, or load to a climbing surface—typically rock, ice, steep dirt, or a building—either permanently or temporarily.

   In rock climbing, a bolt is a permanent anchor fixed into a hole drilled in the rock as a form of climbing protection. Most bolts are either self-anchoring expansion bolts or fixed in place with liquid resin.
