[MCR] Jasper National Park

[Public Mountain Conditions Report]

Heavy rainfall (60 mm in past 72 hours) and above average seasonal amounts
of snow lingering in the alpine have combined to produce several large
avalanches (up to sz 3.5) in the Columbia Icefields Area in the past few
days. Some of these slides continued well below the snowline into the lower
reaches of the slide paths.  The freezing level ranges from 1600m to 2200m,
with only a light freeze expected at the lower end.
Impressive rockfall occurred in Wednesday's deluge, with numerous
refrigerator size blocks ending up on the Icefields Parkway between Tangle
Hill and Mount Coleman.  This phenomena is most likely very widespread and
presents a higher than normal hazard.


River levels are well above seasonal averages both around town and at
higher elevations. The Miette River is three times it’s usual maximum
discharge! Needless to say, river crossings carry an elevated risk with
higher flow rates, deeper water, and increased amount of debris.


With an additional 30-50 mm forecasted for this weekend, it may be a good
time to work on indoor projects.
