CEM Releasable Knot
Construcción y colapso del Nudo CEM en un arco de roca / “El anclaje recuperable Mexicano”
En esta ocasión visitamos el cañón de El Zarco en Zapopan, Jalisco. Un cañón que presenta al inicio formaciones de roca muy peculiares, en especial nos llamó la atención una zona que no presenta gran desnivel pero tiene arcos de roca perfectamente pulidos por el paso del agua. Un escenario propicio para instalar un anclaje natural y en este caso el Nudo CEM ya que el punto de anclaje (Arco de roca) se encontraba a una distancia de 2 metros de la vertical a descender.
The CEM (for Cañonismo En Mexico) is a releasable knot, similar in function to the macrame. It can be used around natural anchors, especially trees, when insufficient webbing is available.

I love this technique! But you have to practice!! This is much more complicated than the macrome but it releases much more easily. I used this technique on a very long rappel as the LMAR. I had to pass a knot on rappel about 200 feet in the air while hanging on this thing. It worked! It was also super easy to pull. We could have pulled it with 2 fingers. Let me repeat…. You must practice this. It’s also good to test it with a safety in place. See the very last picture for where the safety is placed. Of course LMAR must remove the safety.
