So in my real-world adventures, I climb - on nice dry rock- I tend to stay away from slogging in snow or alpine climbing. The equipment and techniques have improved a bit,
...but those old illustrations show the rudimentary technique and equipment of the time, much of which evolved into modern climbing techniques, and a few which are still in use. And they can be very informative for players whose characters' "climbing equipment" is equivalent. That is, hemp rope and a few metal spikes.
