On this index page I have grouped the slides by subject/location
and provided a brief summary to the right. You can click on any
thumbnail image for a full sized page, which will have more of a
description for each photo. The full sized pages also have navigation
bars at the top and bottom if you want to go from one to the next
in either direction. You can find more avalanche photos in the Gallery at Avalanche-Center.org, especially if you are a member.
Avalanche Terrain in
Rogers Pass, where the Trans-Canada highway crosses the Selkirk
Mountains. Defense structures can be seen in the center and right
photos.
Avalanche Terrain in
Kootenay Pass where Highway 3 crosses the Selkirks. A "Gaz-Ex"
exploder for control can be seen in the right hand photo.
Avalanche Terrain and
Defenses above Innsbruck, Austria (left) and paths above the Whitewater
road near Nelson BC. The photo from Innsbruck has defenses labelled
in the full size version.
Snowpack tests - the
"burp test" on the left, the "tap" or "compression"
test in the center, and a Rutschblock on the right.
A full snowpit profile
above the Whitewater road in the West Kootenay region of Canada.
A compression test in
the same snowpit as above.
Snowpack analysis during
a private class in Oregon.
Thin ice layers with
soft snow between caused a weak layer which kept going "whumpf"
under us in this spring snowpack in western Oregon. On the left
the layers can be seen, the center shows how the weakness responded
in a Rutschblock test.
Probeline practice during
a class for transportation and industry interests. Unless somebody
is in a car or structure this is generally a body recovery method
and therefore is not emphasized in recreational classes.
This photo of snow movement
down a chalet roof shows how a snowpack can glide on a smooth surface.
The way it bends at the bottom shows its viscous behavior.
