ACMG Mountain Conditions Report Summary for the Rockies and Columbia Mountains issued September 8, 2016

Well, If nothing else, this summer has been consistent in that most weekends have been difficult to plan from a weather standpoint! And... this weekend appears to be following that trend.

From Revelstoke to Golden to Jasper and Canmore, the forecast seems to have either Saturday or Sunday showing a significant chance of rain. With regards to mountain conditions, the recent snow will be the greatest factor for decision making.

ACMG Mountain Conditions Summary for Rockies and Columbia Mountains September 2nd, 2016

The weekend may not be as "doom and gloom" as some of the forecasts had been predicting but it certainly doesn't look like it will be a perfect weekend for Alpine climbing in the Rockies and Columbia Mountains.

4c and 8mm new rain at 2170m west of Rogers Pass summit this morning. Sounds somewhat similar but perhaps a little cooler along the Rockies divide with snow observed at O'Haracabove 2300m.

Sadly, there are already signs of autumn approaching in Canmore with a few trees already turning!

It looks like another challenging weekend of weather and conditions for mountain enthusiasts in the Rockies and Columbia Mountains.

This past Monday saw up to 20 cm of new snow fall above 2500 m across both ranges. This is gone on most aspects but the cool unsettled weather this week has likely preserved this snow on higher, northerly aspects. There have also been reports of this snow lingering on some glaciers making travel and crevasse assessment challenging.


After a very long spell of unsettled weather and electricity the current forecast is calling for mainly dry conditions with the chance of afternoon showers.

In the Rockies many of the ice faces are starting to look very dry and out of shape with rockfall being the major concern. Glacier travel is a mixed bag depending on the overnight freeze, and recent reports have ranged from great travel with good snow pack coverage, to relentless post holing along glacier flats. The firn line in the Columbia Icefields is around 2700m.

After a wet and snowy start to July, alpine conditions are starting to improve.

In the Rockies, alpine rock routes are in great shape generally. The high peaks like Victoria and Assiniboine still have lingering snow that may inhibit upward progress but they seem to be just around the corner from high season condition. Solid freezes have been rare this summer but as the snowpack thins out further we can be hopeful for this to occur more frequently.

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.
