Very interesting demonstration/explanation of Bernoulli's Principle in mountaineering! Alas, I had to study Bernoulli whilst in ground school, with an emphasis on the dangers of flying near mountains at night in a storm and the grave consequences should one encounter a low pressure zone (false high altimeter reading thus, one might plow into a mountain if flying by instruments)(perhaps a contributing factor in the Gambler's Special crash...I have not looked into it)
I readily admit to being nothing more than a casual hiker with a map & compass, so I am curious how essential -- or widely used -- is the altimeter amongst experienced mountaineers?
