Vibes to the victim and her family.

Here are a few comments. When I worked for CAIC there was a fatal avalanche accident on South Diamond Peak in December 1999. Dale Atkins and I were sent to do the accident investigation. A few years later there was another avalanche accident (fatal) in the same location. We really could have just changed the dates on the first accident report, as it was almost the same exact accident. I wish the CAIC would share their fracture line snow profile from this accident. I'm curious to see how similar they are. My fracture line profile from 19991217 shows 36cm of 4mm size depth hoar and 17cm of 2mm size facets on top of the depth hoar, which was made up of fist and 4 finger hardness at the bottom of the snowpack. If I could find the second accident profile I'm sure it would be just about the same as the first = typical early season Continental snowpack. IMHO, South Diamond peak is a place to stay away from in early winter.
Anybody know where exactly on south diamond this ripped? Kinda looked like gash in the photo but couldn’t tell for sure with the low light.
Hacksaw - where were the slides you were talking about?

Slide location.
The 2000 one looks pretty identical to the one this year. Also, this report from last year: https://avalanche.state.co.us/caic/o...p?obs_id=51763Quote:

Looks like the same place again.
That young man was an acquaintance of mine and the incident fucked up our friend group pretty bad for a while. I think about him, and our friends that were with him, all the time. He was the first of several friends that never came home and a big part of why I don't go out there anymore.Quote:

See the reports.Quote:

I agree wholeheartedly with Hack. This IS NOT terrain to ski in early or mid winter short of exceptional stability.
The thing that I have to say about this area is that almost every time I’m there, someone is doing something stupid.
I’ve seen groups of 7-8 all lapping S Diamond at the same time, multiple people skiing while others lounge at the bottom of the face at the same time, while others are skinning up, all exposed at the same time.
Solo skiers on S Diamond in early winter.
People skiing the face/s in sketchy conditions.
People with no gear
Etc
It reflects a general attitude to that terrain from this particular skiing population.
Perhaps Fort Collins or Cameron Pass needs a remedial Avy awareness focus.
Also with respect to this sad fatality, I have to comment on snow pits. I fucking hate them.
I think that far too many think they’ve gained some expertise by learning them but in reality they are just akin to a first year civil engineer leading the math of building bridges. They may sort of understand the basics but shouldn’t be trusted to actually design bridges.
Even when people get signals from the pit, they far too often only use them to rationalize a GO decision. ‘We DID dig a pit and thought the risk reasonable’

How bout them Bronco's!
I gotta say ... people with way more experience than me tend to not like 'em. Sadly, as you note, they tend to use them to rationalize a "go" decision.Quote:

The two skiers dug a snow pit near the top of the run that they wanted to ski. They correctly identified a slab on top of a weak layer near the ground. They knew that the structure was poor, but the total height of snow where the dug the pit was only 12 to 14 inches. They incorrectly assumed that the snowpack across the entire slope would be 12 to 14 inches deep, and that if they triggered an avalanche it would not be very big. Snow profiles and snowpack tests are useful tools to examine the snowpack structure and identify weak layers; however, use great care in extrapolating a snow profile to an entire slope. In this case, the snowpack on portions of the slope was only 12 to 14 inches deep, but the gully where Skier 2 triggered the avalanche was a perfect place to collect wind-drifted snow. The snowpack was much deeper in the gully and the avalanche wider and deeper than the pair expected.
I dig snow pits all the time. I turned around many times.
But... I see very often the comment: he did not have any avie gear and he was alone.
Avie gear will not help if you're alone.
Avie gear will not help if you're caught in a slide and have massive trauma.
Best thing is not to ski when there's a buried weak layer.
A problem obviously if you live in a Continental climate.
Then you do what marault (i think Bill) said: never ski anything over 25 degrees in the winter in Colorado.

There are numerous stories of folks skiing alone being found by other parties. There is one two threads below this one right now.Quote:

Or you could come across a slide with a single set of tracks running into it, but you have no beacon. Plus, I just consider it best practice to ALWAYS wear it. Otherwise you have to pick a point at which it is safe vs not safe to leave it at home and that seems like a slippery slope.
Having said that, If I'm solo and I forget it, I'm not gonna turn around.
S Diamond has always sketched me out. I think I suffer from agoraphobia in the backcountry. I hate wide open faces and bowls, especially when they are above rock outcroppings and terrain traps. Give me a good old fashioned steep coulie any day.
RIP, sad to lose another snow traveler.
Always carry any gear, solo or not. I've had to dig myself out, I've dug others out too, while solo. We even wear gear when skinning jeep roads despite the wife's protest.
yup. maybe if you live above the arctic circle or someplace like that it doesn't matter, but in CO/UT/WY/CA/NV/ID etc, you ain't the only one out there.Quote:
