Keen mountaineers Will and Si joined me at the weekend for some intensive navigation training. They are both determine to have a productive winter and hoped that a pre-season refresher would stand them in good stead. Strong winds on Saturday and a very high avalanche risk meant we had to abort our plan of going high and drop down somewhere lower where we could work productively and safely. Both the guys were already pretty proficient navigators allowing me me to introduce some more advanced techniques which culminating in a couple of hours micro nav in the dark.
