My name is Steve Nichipor. I'm a professional mountain guide with Bretton Wood Ski Resort and I'm going to show you how to anchor and tie in when rock climbing. How to anchor and tie in is a critical skill when rock climbing. There are a lot more possibilities than we'll be able to cover here so we'll just go over some of the basics. As always with climbing, seek out instruction from an AMGA certified climbing instructor before trying this on your own. To tie a knot that most climbers use is the figure eight follow through knot. It is a strong, reliable knot that is easy to recognize when tied neatly and correctly. Begin by making a bite or bend in the rope a few feet from the end. Make two twists in the rope and feed the tail back through the first loop. You should end up with a neat, obvious eight. Next, pass the end of the rope to the tie end point on your harness. On most harnesses this is a reinforced section on the leg loops and waist belt. To complete the knot, retrace the end of the rope back through your figure eight. Dress the knot, removing any twists and tighten each strand. You should have at least six to eight inches of tail when you're finished. Anchoring is a complex skill so we'll assume you've just finished leading or following a pitch of climbing and are already built a redundant equalized anchor with a master point. There are many ways to anchor in at the top of a climb, but my favorite is to use the climbing rope itself. Begin by placing a locking carabiner in the master point of your anchor. The most versatile knot to use here is the clove hitch. This hitch is made by making two parallel twists in the climbing rope. Slide one in front of the other and clip both loops through the locking carabiner. There are many ways to get these loops wrong giving you a girth hitch or just some loops in the rope. So make sure you know how to do this properly before trying it on a climb. Lock the carabiner and then you can adjust the length of your tie in easily.
