16. Creating V-Thread Anchors
In this video we review how to create, and rappel from, a v-thread anchor. A v-thread anchor is drilled into the ice in a V shape, using only a small length of cord which is left behind.
Below are the steps for creating a v-thread anchor:
Step 1: Using a longer ice screw (22 cm), drill a hole at a slight angle in the ice.
Step 2: Remove the screw and place another screw or your v-thread tool in the hole so you can approximate the angle at which to drill the next screw in order to intersect the first hole at the bottom.
Step 3: Drill the second hole at an angle, looking down the shaft of the first hole to identify when and where the new hole intersects the first one.
Step 4: Blow out any debris from the hotel to make it easier to thread your cord through it.
Step 5: Push one end of your cordelette into the hole, and with the sharpened hook of a v-thread tool, pull it out the second hole. Cut the cord to length so you leave behind only minimal equipment. Tie a Flemish Bend or Double Fisherman’s to join the two ends together.
Step 6: Thread your rope through the loop of cord in the v-thread anchor and you’re ready to rappel!
Note once again that the ice quality will need to be factored in when deciding whether to rappel off a v-thread anchor system.
Good = Cold, Clear, Dry, Consistent color and texture
Bad = Soft, Warm, Wet, and Aerated or pocketed

Please remember, climbing is inherently dangerous. Climb at your own risk.
