small bug: after going up the mountain and pulling the rope off the cross-cutting route, it stands to reason that the piton close to them should also be taken down and taken away, because it looks like their piton And quick buckles are limited and must be used repeatedly as much as possible. When going down the mountain, Andy touched the rock nail and cried out: "Cross the route", the rock nail was not removed. This looks like a small bug. It may also be : 1. In order to mark the route or use it when retreating or for whatever reason, according to a certain section of the mountaineering specification, the pitons that cross the two ends of the route must be kept on the rock. 2. In order to make it easier for the audience to understand "they are here to pull the rope "
Small question: If a person retreats and descends from a high place, there is only one 60-meter thick rope that must be used repeatedly. How many meters can he descend in one cycle? 30 meters is easy to understand. Fold the thick rope in half, descend to a 30-meter platform, draw the rope, (similar to a "cross-cutting route"), and continue the cycle. The question is: Is it possible to descend 60 meters at a time? Is there any way to drop 60 meters at a time with the "original equipment" of 1936? Or what equipment can drop 60 meters at a time?
Understand, thank you!
