inclinometer is a device that measures the angle of inclination – in
this case the steepness of a slope. There are lots of fancy and
sophisticated inclinometers available, both analog and digital, but they are
large and cumbersome. Here is a very simple inclinometer, printed on a
sticker and wrapped around a ski pole.
A measurement is
taken by holding the ski pole loosely between two fingers, allowing the ski
pole to swing freely like a pendulum and settle in a vertical position.
You then eyeball the side of the slope against the lines on the
inclinometer. See which line on the inclinometer most closely matches
the angle of the slope.
highlighted area indicates the zone where most avalanches occur, on slopes
between 30 - 45 degrees. Consider that the danger zone. Avoid
skiing in such places, especially immediately after a snowstorm or after a
sudden warming trend, which is when avalanches are most likely to happen.
I did not invent
these gadgets, but once I heard about them, I drew my own design using Corel
Draw. The picture that illustrates its use was taken at Mt. Hood Skibowl on
a day we had a PACRAT race there. That's Doug Pilcher in the photo,
skiing on the Bob Strand's Downhill trail, above Dog Leg. The mountain in
the background is Mt. Hood, Oregon.

Alternatively, you can print your own.

Then print it, preferably onto an Avery 5163 sticker, 2" x 4" in size.
Or, print it on any kind of paper, cut it out and glue it to you ski pole.
For additional protection, it is recommended to cover it with clear
(transparent) packing tape.
