How to Tie an Alpine Butterfly Knot OR Media Mariposa

The alpine butterfly is easy to tie and has diverse uses. Because it can be loaded in three directions, it is commonly used for creating tie-in points in the middle of a rope or isolating a damaged section of rope in an emergency. It is also used for equalizing anchor points for rappel lines. Its shape is readily recognizable, which is a good feature because an incorrectly tied knot will be obvious.
