Monthly Reference Chart
|
|
|
This chart gives a general guide as to which time of year might be best for skiing various routes
on the Cascade volcanoes. The strongest influence affecting these dates is the depth of the snowpack, which can
vary year to year from as little as a half to as much as double the "normal" values. This can shorten or extend
the skiable season by several months, so be sure to check my Cascade Snowfall and
Snowdepth page for current snowdepth info throughout the Cascade Range from northern California to
southwestern British Columbia. In addition, it is often the case during spring that the ski conditions might be
fine on a route, but the roads accessing the trailhead may still be snowed in or blocked by fallen trees or
washouts. This can turn otherwise simple trips into brutal struggles and memorable (mis)adventures, so it is
best to get current road closure info from the nearest ranger station or from the website of the relevant
National Park or Forest if available (these links are listed near the end of the page for each peak, and also on
my Web Links page).
Most importantly, one should check the avalanche bulletins and track recent weather trends. Many
of these routes may have severe avalanche danger at various times, especially during the winter and early
spring. Even though spring is the prime season for ski mountaineering, despite generally reduced avalanche risk
it is statistically the most dangerous time of year for avalanche fatalities, due to increased carelessness. In
late spring and summer, the avalanche hazard is generally greatest during the hot afternoons, so it is best to
make an early ski descent (and corn snow is much better to ski than glop). Various useful avalanche links can
be found on my Web Links page.

Key to this chart: |
|
|
|
Optimal months, assuming normal snowpack |
|
Marginal months, could be good or even great with above normal snowpack |
|
Skiable months, but roads to the trailhead are likely to be snow-covered
for a long distance |
|
Unlikely to be continuously skiable in an average year; however,
on most of these routes snow patches do linger well into or even throughout
the summer, so short runs may still be possible |
