Mountain Conditions Summary for the Rockies and
Columbia Mountains issued July 27th, 2006
It is now approximately the sixth week of summer
conditions in the alpine and the hot, dry and getting icier trend
continues.The snow is still melting quickly, especially below 3300m and ice
is starting to melt signifigantly on the margins of ice faces and glaciers.
Actual snow travel conditions vary greatly from day to day with solid freezes
and morning slush all being possible.
Rockfall from the rapid melting of snow and
especially of old ice is arguably the biggest hazard right now. As the ice
faces and steep glaciated terrain melts out some REALLY ugly terrain is being
exposed. Big blocks are left perched in precarious positions and they are
looking to find a new home somewhere downhill.
Pure alpine rock routes are generally bone dry with
some rare exceptions at high elevations. Snow and ice routes are getting icier
by the day and bergschrunds are slowly opening up. The big mixed routes are
generally in terrible condition right now, dry with lots of rockfall, dirty
ice and exposed choss. Glacier travel is mostly excellent but alpinists
need to be prepared for both bare ice and poorly bridged crevasses,
especially in the daytime heat.
There is some possibility of rain in the
weekend forecasts. Light to moderate rain isn't going to change anything
dramatically in the snow but obviously it will be weak when rain soaked. We
haven't had many big thunder and lightning events this summer
but watch the most recent forecasts when planning your trip and the
upwind weather when you are out as this could be an electric
weekend.
