Downclimbing is when you climb down a drop in a canyon without the use of a rope. Downclimbing is a skill that can increase your speed, but it also increases your risk. Sometimes it is beneficial to have a competent downclimber act as a meat anchor so that some of the group can rappel down a drop. Then the downclimber can drop the rope and climb down. This saves time setting up a retrievable anchor if there are no fixed anchors.
