Introduction
Due to the ever increasing number of winter
backcountry recreationalists, avalanche awareness and safety has become
more of a priority than ever. In 2004, North America suffered its
most fatalities ever with 34. It is obvious that avalanches
are hazards that should not be taken lightly. Although the
science is technically rigorous, avalanches continue to be impossible
to predict and require us to have a thorough understanding of the
basics. For example,
ADFAR
is one of the many initiatives of the Canadian Avalanche Association
that provides one with new techniques and methods for making better
decisions when traveling in avalanche terrain. The goal of this
particular project is the design of a simple tool that can help
backcountry users manage their risk in the mountains, and help at home
when planning winter outings.
Team Depth Hoar would like to emphasize the impact of
the snowmobile on avalanche related fatalities. With the
insurgence of the snowmobile
in recent decades, this recreational activity has taken more lives due
to avalanches than any other activity. It has never been easier
to access the backcountry with these machines.
The
Rogers Pass
area of southeastern British Columbia perfectly exemplifies the
hazardous nature of avalanches. Ornamented by the Selkirk and
Monashee mountain ranges, Rogers Pass is outlined by the Kootenay
communities of Revelstoke to the west and Golden to the east.
With the implementation of the avalanche control center, located across
from the Rogers Pass information center, the number avalanche
fatalities has dramatically decreased to almost zero. Public
awareness of avalanches in Rogers Pass has been driven by media
attention, particularly in the case of recreational activities.
On February 1, 2003, seven students from Strathcona-Tweedsmuir High
School in Okotoks, Alberta were killed by an avalanche in the Rogers
Pass area while on a field trip. Controversy surrounding the
event spawned from allegations that the school had not taken the proper
precautions in planning the field trip. Cases like this bring
forth the significance of a need for avalanche awareness.
Although world-wide standards have been established
assessing
avalanche slope stability, there still exists many differences in
which the way this information is broadcasted. In Canada, we have
been blessed with the daily avalanche bulletins of the
Canadian Avalanche Association.
The Canadian Avalanche Association acts as a Canada wide database where
all avalanche related data can be found. However, in the US
there are several "avalanche centers" where often, it is difficult to
obtain data if you do not know where to look. This can be
especially confusing for people trying to plan a trip who are not from
that particular area. This is a problem that
certainly needs to be addresed and is discussed ->
here.
