Rappelling station in ice that can be easily dismantled

A crosswise placement of ice axes for rappelling in hard snow for easy dismantling. Note how the appearance of the ice axes is less clear in comparison to the idealized illustration above. The loops of the ice axes do not make the arrangement clear, and for this reason a person must be careful when constructing this rappelling anchor. At the beginning of the video, there is a brief example of the strength of this anchor, which can withstand even a sudden hang in the rope. There follows the dismantling manoeuvre accomplished by retracting the rope, and the automatic dismantling of the anchor point.
