How often does it avalanche in Niseko and where are the most prone slopes?

Pretty please??

?

Evidently not worth the effort in answering, but in the real world it's fairly good manners to say thanks or cheers or please or something similar when asking something of someone.

I read a few of your posts and none of them had a please in them. A little hypocritical don't you think?
Are you also the guardian of this forum then?

For the record to everyone else, please and thank you in advance.

Hornster, Powder Ski has a great article in the current issue. The last avalanche in Niseko that killed somebody was 1999 and it was off the peak that everybody skis. There were 8 deaths from 1985-1999 (when Niseko local rules was implemented) anywhere from Mizuno Sawa, Haru no Taki, the back bowl, etc. There are avalanches at Niseko so dont be fooled. But, patrol up there, Niseko Nadare (avie) group, and a few other organizations daily digpits, assume risk, and decide whether to close areas off or not.

For all of you reading this out there, if there is something closed at Niseko, its for a good reason! I hope there arent punters out there reading this (or not) who go off and ski the back bowl without avie gear. Dont be stupid.

Niseko Local Rules were created because people jumped ropes regardless of what patrol did back in the day. So, to protect themselves, as well as riders, they took down (most ropes) and check avie hazard daily, kinda like what you get on the forum for the Hakuba Now! report. Those guys who do Hakuba Now and also the Niseko crew are closing areas for a good reason. Now, if its blocked off, it appears most people dont go riding it because knowledge as diffused enough over the years that powder hunters who go there trust what patrol says to be accurate, rather than just keeping you out of the area cuz its not safe. Thats kinda what makes Niseko ahead of the game, theyre proactive in avie control, rather than just saying its dangerous or you cant go in there cuz its outta bounds.

tired so hope this makes sense.

The snow pack in Niseko is remarkably stable considering the amount of snow we receive. Of course they can and do happen but within the resort boundary and in the allowed off-piste areas there has never been a death from an avie as far as I know (at least since the Niseko Local Rules were implemented). Where do they occur? In all the obvious places they'd occur on any mountain in the world. Areas under cornices or below convex slopes or where there's large amounts of wind deposition. The gates allowing you into off-piste areas are pretty well managed so if you don't duck ropes and have a little knowledge of danger signs then generally avies pose little danger in Niseko. The main season we get big avies is in Spring when full thickness slabs can release down the bowls. I've seen a few shallow slides in winter but nothing serious enough to completely bury anyone.

Thanks very much for the information. I was just curious because when I was out in Niseko last season for a week I didn't see, hear or know of any avalanches. I did think that the very top of the mountain at Higashiyama and Annapuri looked like the ideal type of slope for avalanches if the conditions were right.

I spent a season in Revelstoke in BC many years ago, working for CMH Heli-skiing. It's an area that receives similar amounts of snow (if not more) than Niseko. Avalanches were a daily occurrence there and you could often see and/or hear them from town. I did a fair bit of backcountry skiing out from Rogers Pass and it was seriously scary at times. I and two others did get buried in an avie whilst heli-skiing one day (no one died luckily).

The main difference between here and there is the variation in weather. The Pacific side of the Rockies has extremely variable weather conditions like snow to sea level one day and rain to over 2500m the next. This can make for very unstable layers in the snow pack. Niseko on the other hand has sub freezing temperatures for pretty much the whole winter with it rarely getting above -10 at mid mountain from Dec through Feb. Niseko also gets few clear days or nights meaning there's little sun or hoar frosts affecting the surface. Also the snowflakes here in winter are predominantly fernlike stellar dendrites whose fernlike structure bonds well with other flakes making the snow pack quite stable. Anyway I'm no specialist but these are my observations.

For someone who considers themself not to be a specialist in this field you certainly seem to know what you are talking about. Thanks again.

What I enjoyed about skiing in Niseko was that there is just so much powder in the in-bounds off-piste areas that there is honestly no need to duck ropes to ski powder. I tend to get up early with the first gondola etc so I always get first tracks everyday. I suppose that if it is fresh tracks that encourages people to duck ropes then the simple answer is to get up earlier!

Just wanted to say a big thank you to GN and CB for sharing thier knowledge on this topic.

Great information and will help educate a lot more people than just Hornster (thanks for asking the questions Hornster!). I know I have heard/read a lot of that info before, but I understood more of it this time. Can't get too much Avie knowledge really can you?

Ditto

This is simple. There is no such thing as avalanches in Niseko

Just for those coming in late and reading that last comment, zip up to the other valid comments.

Wasn't there one that took out a light pole last season

Funny Okemo

- but for those who are not aware that you are taking the p!$$ re terrain - if it snows it can slide.

Yes some area's are a bigger danger than others, but it is not worth heading out to the slopes of even a 'safe' resort believing it can't happen. THAT is how people get caught up in disasters that could have been avoided. Like the young bloke who died in Aus this season who walked out onto a cornice on a lovely warm day - and it gave way below him. With a bit more knowledge he might not have ventured out there, trajedy might have been averted.

There is no such thing as asking a stupid question - and there is no such thing as too much safety knowledge.

The whole of Japan has a maritime snowpack. I have always been surprised that the snow in some places is advertised as "champagne". It can get extremely light at times similar to continental areas, but it is not the norm. Maritime snowpacks tend to be more stable than continental packs such as in the rockies. The shear depth of snow helps with regards to temperature gradient except early on in the season, but as mentionned earlier the high variability of weather can make it very tricky as well. Mr. Wiggles is the pro on all this so may be able to add.

A season in heliskiing in the stoke must quite the experience GN.

Your right, I did see the snow slide off the roof of my hotel in Niseko. PSA Be sure and wear your beacons while walking to and from the resort.

But, Okemo, there is such a thing as being too silly for words.

TBH, I always thought Niseko was too flat to be able to have avies...
