Digging snowpits |
On Sunday March
9
th , 2014 we wrapped up an Avalanche Skills Training (AST) course which
was held in Corner Brook for a group of 7 avid backcountry skiers, snowboarders
and snowmobilers. We had a great day for the field work component which
involved beacon searching and probe line practice as well as snowpit analysis.
We dug 3 separate snowpits on a lee slope where snow depths were around 130-140
cm. We performed a variety of stability tests including a shovel shear,
compression, extended column and we even got in a rutschblock test.
Most of the tests showed moderate stability of
the snow at the test site. If anyone is interested in more information on
avalanche awareness training in Newfoundland then contact Keith Nicol at
knicol@grenfell.mun.ca This year the
awareness training is being subsided by the Canadian Avalanche Centre (CAC) and
includes sessions that run anywhere from 1 hour to 2 days. Thanks to CAC for supporting avalanche awareness training in Newfoundland in the winter of 2014.
