NAPADS great for Natural Hazards and horrible for Deadly human triggered avalanches an avalanche professional dies every year in North America a guest in managed operations every year in North America in return avalanches with a shallow weak layer and concurrent activity REGARDLESS of slope within the alpha angle. Non-Rated dangerous observations of shooting cracks, collapsing and whumpfs often observed. Physics of Natural Hazards avalanches different from deadly human triggered avalanches. NPADS implementation in 1992. Demographics of avalanche deaths radically changed since then. NPADS focuses on crown and NOT on the source or origin or trigger of deadly events often 10s 100s even 1000s of feet from crown.

Thanks! Really helpful and informative.

It's always a excellent idea to wear your Avalanche Transceiver in the transmit mode under neath your 1st layer and bring your shovel and probe in your Backpack.

Biggest takeaway to share with friends who are interested in going into avalanche terrain are the Red Flags mentioned: Recent Avalanches Recent Snowfall or wind loading Cracking or whumpfing Rapid Warming

We're expecting >30cm tonight. The cascades are getting hit. Keep up the good work.

Thank you, NWAC. I appreciate you all so much!

Respect! Thank you for allowing me to tell your story 😊

Love your forecast and details. Thank you for keeping us safe!

thank you NWAC for all that you do keeping us all safe!

Incredible what you all do, thank you!

Nicely done clip. Thanks for your work

Would love more videos like these!

Great video! I'll be sending some of the rookies I meet as a mentor to this video in the future!

Thank you for publishing this! Very helpful and educational.

This is great. Thank you for this new feature.

This is an awesome exercise session.

What are the chances y’all start making these videos more routinely? The forecast is amazing but these videos could be an invaluable supporting tool for us, especially newer folks to avalanche safety

The mountains are indifferent to our human suffering.

Rebreathers and GPS emergency radio transmitters and loud beeper?

15' away and would have never found his friend. That's so saddening.

These images made me wonder. Is there such a thing as "slope loading" or "cliff loading"? In other words, could snowfall roll down that cliff and make snow deeper right below it, during the storm? That crown seems very thick.

Thank you and peace be with the families.

My heart goes out to the families affected by this. Thank you NWAC for the information. That 4-6' crown is shocking to behold.

Thank you NWAC.

Tragic, this one hit close to home. Thank you for the information. Was there any info on what transponders were used?

Condolences to the victims family🙏🏻🙏🏻

Thank you so much for your support with the Snowpack Scholarship program and also continuing to mentor females to advancing positions in avalanche education.

Happy Birthday Paul : )

Well put together,no high tech words were used so a person didn't have to carry around a dictionary to find out what she's talking about.Wish I had her speech on dvd.

Good data. Is that Integral GIS NW Avalanche Atlas available to the public?

this is as fucking boring as shit drying in the sun...

You city people think too much.

I’m curious as to how WTR boots test with WTR rated bindings. Any results?

I have considered removing the brakes from my Radical TLT's to make it easier to rotate the heel piece out of the downhill position using a ski poll but should you remove brakes on Radical bindings since they are built with an Anti-friction devices?

WOW excellent ! Thankyou for this.

Thanks, great study! Have you tested the Dalbello GripWalk system? www.dalbello.it/en/technologies/gripwalk/

Nice, impressive work.

Great study. Now I have an excuse to buy more gear! Seriously though, excellent work.

see kodnerlab.wordpress.com/ and www.vikingfunder.com/project/3177 for more information

Jeff great info, The topic just came up for staff, so it very useful. As I have followed ASTM for 25 years, I found the information very useful.

Nice info, thanks!

Friends don't let friends ski with the toe piece locked. Practise taking your skins off without taking your skis off to prevent snow from packing your inserts. Consider unlocking your toe piece when walking across dicey spots.

Great information, but one huge mistake/misconception regarding the ABS graphic he uses (airbags in general). Airbags DO NOT work on the principle of buoyancy! They work on the principle if "Inverse Segregation"!!

Great video! thanks for sharing

old news

Great stuff Jeff! Shared the crap out of this, keep up the great work!

Can no one at NWAC hold their phone sideways? I kid, you guys do great work.

Cracks, weak layers in pits- were you able to produce an avalanche anywhere there? If not does it matter, if it matters, why? Certain specific areas are more wind-polished due to aspect and location on the slope, then the next storm may have fresh deposition without wind, perhaps the slope with cracks over toward the windward side? Was the cracking slope representative of the entire slope that produces avalanches? Were the active avalanche paths cracking as well, or running- avalanche? The main slope that you described is 37 degrees at the starting zone, and the more active bowl further away a little steeper and more active. I will interject here to say that to leave the impression of that path below Diamond Point is 20 degrees is far off and a dangerous idea- a few feet away from your 20 degree slope is a major avalanche-producing slope in the sweet spot of angle 37 degrees and a snow deposition zone. I have kicked there a Size 2 for hundreds of feet, and have seen where it fell Size 3 from natural avalanche 600 to 700 vertical feet.. You chose to pit a part of the slope with 20 degrees angle, you say, (above the breakover), which will not avalanche- why? Further in the video-it appears that you have chosen an area to dig a pit that is not in an avalanche starting zone; again why? A pit not exactly in a specific avalanche starting zone gives data that does not meaningfully correlate to avalanche hazard evaluation. Pockets of buried facets always exist on that ridge and elsewhere in certain shaded or wind- protected locations. To be significant, these buried weaknesses must be on terrain that will produce an avalanche. Posted by Rob Mullins.

Stay safe out there all. Thanks Tom!

eekk. Thanks Jeff!
