Benjamin, how to cross a glacier

Dangers of crossing a glacier
blindness  where excellent glasses or you'll be blind in a day
weather (duh)
===summer===
big danger is the crevasse.  More ice movement, whichleads to giant shifting openings. Depending on how big the glacier is they can be wide and deep (on theorder of 300 ft)

if you call in, it will be hundreds o fyears before you are oufnd

===Rules===
*You need a rope.  the longer the better, ( more time to react when someone falls)
*atleast two people, tied together with the rope.  the more people the better
*you must wear crampons
**let say someone falls in.  
*the rope must be knotted.
**the rope will cut into the ice.  the knot will catch and make it easier to support dead/dying weight
**this is also where crampons come in handy
**if you can hold them steady, and there is a rescue crew, just hold tight.
**otherwise, they have to get out on their own.
***impossible to pull up on your own.
***they must climb on their own, but this takes a wile, and 30 minutes is a long time fo rther person on top to hold dead weight.
***use your ice axe

====Winter====
safer
*and you'll be on skis
*crevasses from prev summer are all fille din this snow
