When we get into uncertain alpine terrain, things can change quickly. Terrain features can change, snow and ice coverage can change, and weather is more dynamic. Any of these changes could confront us with a pitch that might be too hard to climb given our current footwear and carried equipment. Rather than turn around, this improvised gear and movement sequence may help us continue on our climb.

Like most things in climbing, what is "safer" depends on circumstance. In this case, we are looking at rope blocking options: knot blocks, carabiner blocks, and the Reepschnür hitch (and some of the modifications to it) in order to explore the security at the rappel (abseil) anchor point versus ease of retrieving our rope.

The short answer is, "no, you cannot make the perfect crevasse rescue anchor." The inherent tradeoffs between speed and anchor strength and adaptability mean that we have a series of risk-mitigating decisions we need to make before we ever start hauling our climbing partner out of the crevasse. Let's take a look at those tradeoffs so that we can make the best choices we can should we ever really need to make them.

When we want to change lead climbers on a glacier, we have to do so in a way that still protects the team from crevasse falls. Here are three methods for getting a trailing climber into the lead position.

A 6-to-1 crevasse rescue system, or a "z-haul" on the back of a "drop loop," is a flexible system that can mitigate many of the problems that arrive in various crevasse rescue scenarios. In this video, we demonstrate setting up and using the base system given a team of three climbers.

We have fallen into a crevasse that is overhanging. We are free hanging, unable to touch the wall. We are tight against our knot, so have little rope slack to work with. What do we do first, to stabilize our situation, and then how do we ascend the rope to self-extract?

If we have a climbing partner injured on rappel (abseil) who is weighting the rope, how can we get quickly down to them to render aid? Here is a method that has evolved over time.

Every May, we make videos on the mental side of climbing and adventure in recognition of National Mental Health Awareness Month. This video talks about close call assessments, discussing what they are, who uses them, how they can make our climbing safer, and walks through a low-effort way we can apply them to our own climbing.
