I guess it's a bit different here in Europe then it's over the ocean. All what I wrote, was meant for off-piste skiing.
This thread is specifically about wearing a beacon
inbounds . No one (I hope) is debating wearing one out of bounds.
So yes, to be clear: “
inbounds” in this sense means terrain that is
patrolled and controlled for avalanche mitigation.
In North America that is the
entire area within the ski area boundary. In Europe that
only means the groomed pistes and controlled “ski routes” (meaning the ones marked on the resort map and one the ground with signs, not a ‘route’ published in a guidebook).
I find it best not to use the term “off-piste” in North America, since it is very unclear: it could mean ungroomed but controlled terrain or it could mean uncontrolled terrain outside the boundary.
Even in Europe it can be ambiguous: Is a mogul run “off-piste”? What about one of the above mentioned “ski-routes”?
Basically there are 2 aspects that those terms are meant to convey:
Surface condition: ie: groomed vs ungroomed
Safety condition: ie: patrolled and controlled vs uncontrolled and unpatrolled
The reason the term “off-piste” is confusing, yet widely used in Europe, is that the vast majority of terrain that is controlled is
also groomed, and vice versa, so the term has come to have this double meaning.
This is why I suggest using the terms (even in Europe):
Groomed (groomer, etc)
Uncontrolled (slack-, side-, backcountry)
