Edward Whympers words are still worth remembering today:
“Climb if you will, but remember that courage and strength are nought without prudence, and that a momentary negligence may destroy the happiness of a lifetime. Do nothing in haste; look well to each step; and from the beginning think what may be the end.”
These days there is no excuse for poor belays as the equipment we carry is nowadays so good, thankfully there are fewer accidents nowadays with belay failures. The advent of climbing walls means many climbers learn to climb inside where everything is simple. When you take your skills out in the big mountain routes things change. Always take time over your belay and use at least 2 separate points. Always check even if the belay has been used before is it still a strong belay, I have found on several occasions that what was thought to be a strong belay was a loose rock. There is so much written on the climbing forums and instructional guides it is easy to learn but the best way forward is to get out and climb. The mountain cliffs do not seem so busy maybe it is the weather and or are climbers not so interested in the full mountain experience. It is worth noting that all this rain could produce loose rock, be aware. On this point I would always were a helmet on a mountain route, there is no excuse nowadays as they are all so light and comfortable nowadays, unlike when the photo was taken below in the early 1950’s.
