Hey I got the title honorary glaciologist (professional). That's just
the qualitative stuff.

Spring is not a great time of year to study mass balance. Movement is
also sometime complicated.

Well post WWs you had lots of explosives around. You got your Monty
Atwater types and Jacques Cousteau types tossing hand grenades and
shells. People forget that John Hunt took a 60 mm mortar to Everest to
deal with the hazard. At the end, they didn't want to carry all that
ammo back, so they used it all.
You had all those 75 mm pack howitzers, they ran out of ammo, so they
went to 106 mm recoiless rifles and 105 howitzers (several people I know
own these) and again little to no ammo now, so that's why they have to use
Avalaunchers(tm) now. Hand charges have replaced grenades. Baker used
to toss those. Remember him? In central Oregon now. Doesn't have to
think about usenet any more.

I saw the flat.
I saw last years' AAJ and people like to pitch tents on platforms
chopped out of knife-edged ice ridges with 1,000s of feet of air on each
side. Always have 1 corner hanging in space.

If you have enough snow, Sure.
You must have spacing between the boulders.

Chouinard in his Climbing Ice book did his Nov. Mendel ascent. I know
what he was talking about leg breaking postholes.

Some.

3 good sized ones.
They have mountains buried in them.
