ACMG Mountain Conditions Report Summary for the Rockies and Columbia Mountains issued July 15 2016

In May most people were saying that we were a month ahead of schedule and now we seem to be a couple of weeks behind!

The relatively wet, unsettled and unpredictable weather has made for challenging conditions throughout the Columbia's and Rockies of late. The forecast for the coming weekend looks to be equally challenging.

Saturday is forecast to be rainy throughout the forecast area. Sunday is currently a bit of a question mark for the more eastern areas but looks like it could be a bit dryer further to the west (Rogers Pass and Revelstoke).


The Rockies have seen some good alpine conditions when the overnight freeze permits. In the Columbia Icefields multiple routes on Athabasca and Andromeda found good travel while its cool with snowline being encountered at around 2550m. Sags on glaciers are quite apparent and most bergschrunds are still quite passable with minimal difficulties. The main concerns listed by ascents were exposure to cornice hazards and an increase in avalanche danger as the day heats up.

ACMG Mountain Conditions Summary for the Rockies and Columbias June 15th, 2016

Wintry day in the Rockies alpine. Never got above freezing in the alpine and was cool in the valley bottoms. Lots of signs of recent windslabs in the alpine, looked to be 20 to 30 cm thick. No reports from the Columbias but I would assume it is a similar state of affairs.

The wind is still blowing and the snow is still falling at O'Hara as of 3pm. The snow will melt fast when the sun comes out but there will certainly be a cycle of at least loose wet avalanches and rockfall before things get back into shape again.

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains issued June 10th, 2016

From all reports it is currently a grey damp world in the Rockies and Columbia mountains. Information is limited but it seems that above treeline in the Rockies somewhere between 5 and 15 cms of snow have fallen. Limited reports from the Columbia Mountains show rain at Treeline and probably higher.

The new snow and wind may have built windslabs in alpine areas. In the Columbia Mountains and the Rockies any rain should be assumed to have weakened crevasse bridges, cornices and shallow snowpack areas.


In the Rockiest this past week people have been getting out between storms for alpine climbing in areas such as the Columbia Icefields. Reports from both Athabasca and Andromeda found decent travel, but it is definitely still wintery above 2800m which is true for the Rockies as a whole. An avalanche fatality in Kananaskis Country this past week is an unfortunate reminder that many features in the alpine still hold enough snow to avalanche, and that snowpack and terrain choices should be evaluated throughout the day.

ACMG Mountain Conditions Report Summary for the Rockies and Columbia Mountains issued May 19th 2016

Hello everyone

The well needed current and forecasted rain seems to be widespread throughout both the Rockies and Columbia Mountains over the weekend. Although people were still enjoying good alpine climbing and skiing conditions on some of the higher peaks of the Icefields last week, these conditions will have changed dramatically.

ACMG Mountain Conditions Report Summary for the Coast Mountains issued May 13, 2016


One report of a flight over the SW coast (Squamish to Meager) observed significant melt out below treeline but lots of coverage in the alpine still with no suncups yet so likely good turns still to be had. Lingering cornice hazards with a few large er avalanche events estimated in the last 36-72 hours and interesting glide cracks.
