[MCR] ACMG Mountain Conditions Summary issued August 13th, 2009

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains issued August 13th, 2009.
 
The mountains are in generally bare and dry summer condition right now. Obviously rain and some high elevation snow is making a mockery of that statement at this moment:) However, bare ice, no old snow and lots of exposed choss around the glacial margins is the reality.
 
The recent posted photos of the Bugaboo/Snowpatch col and the subsequent rockfall there are dramatic signs of the times. I believe I have heard more rockfall horror stories this summer than any summer I can remember, and the vast majority of these were from the retreating glacial margins. There is still lots of fine, relatively safe climbing, mountaineering and glacier travel to be had but you need to keep your eyes wide open as well as your plans. Routes ranging from most of the classic ridges to some of the Bugaboos big walls are excellent objectives right now. The trick is getting onto those features through reasonable terrain. Rain, daytime heat and other parties are the obvious factors that can exacerbate the rockfall hazard.
 
Many ice routes have deteriorated or disappeared for the time being. I feel that routes under ice faces like the North Face of Alberta should be assumed to have an unacceptable risk of rockfall for the time being.
 
Glacier travel is getting trickier in most places. The thin snowpack that remains is great with a good freeze but spooky when it is moist or wet. It is definitely time for disciplined glacier travel with a snug rope and some knowledge of how to use it. Lots of bare ice around so make sure your crampons are snug and sharp and that you are very aware of the consequences of a roped or unroped fall on moderate ice. Can you really hold your partner if they fall on moderate angle ice?
 
Front ranges are well clear of old snow and the rock climbing and scrambling is drying out quickly. Even in the dry ranges reports have spoken of increased rockfall activity.
 
Wear a helmet but keep in mind that will only save your hairdo if you get hit by one of the pianos or refrigerators that are rolling downslope from time to time.
