Depending upon your part of the world, winter climbing can bring extreme cold that can make the seemingly simplest things complicated. I got asked a question about how we stop our drinking water from freezing when temperatures dip into the extreme. We can borrow lessons from many high altitude climbers who regularly face those types of extreme temperatures.

When winter sets in, the cold, the gloves, and the snow and ice all make tying and - particularly - untying weighted climbing knots more difficult. So, easier-to-knots to untie can make transitions in and out of systems faster. Here's three ways that I start using a bowline on a bight when wet, winter weather shows up in the mountains.

While the "backside clove hitch" method of connecting to the anchor is getting more and more popular for ascending routes, we can extend that same thinking to a multi-pitch rappel. The method was developed to address the problem with managing knots in the ends of our rope, as we need to remove them to pull the rope but need to add back for the next rappel, which creates opportunities for mistakes. Here's how it works.

Like the old "choose your own adventure" books, each climb we make presents many choices, big and small. Let's look at two different transitions, moving from climbing to rappelling in a team of two, to see how our choices impact the various risks we can both avoid and bring into play by those choices.

Counterbalanced simul-rappelling is something expert climbers will do in unusual circumstances, and this gives the impression of relative safety. But in nominal climbing circumstances, what benefit are we really gaining? We break down the time-savings benefits so that we can weigh the costs.
