    if you look at the 'related links' below it says they already had 17 ski area deaths this season as of april 6th..
    beating the previous record of 16 deaths from 2001-2002... so now it's way past that

    This was outside of the Loveland ski area boundary so it technically does not count.

    Sad story. The report and local avalanche forecaster claims that they were being safe, had the gear, and were spaced properly. This must have been one hell of a slide, crown was 8 feet deep I think? That is massive.

    colorado is colorado to me.
    wondering if the likelihood for avalanches is more common in spring?
    i would imagine you get an ice layer after a warmer day, then the next snow kinda rests on the surface of it instead of bonding with the previous snow.

    that is the most obvious possible sliding bed surface but not the most dangerous, often spring storms come in warm creating a strong bond between the old bed surface and new snow. A typical spring melt freeze cycle creates some of the most stable conditions until it gets real warm toward mid day or late afternoon and there are good conditions for wet slides. It doesn't sound like Colorado has had a good mf cycle this spring, this slide stepped down 8 feet meaning it went down through many layers to rotted depth hoar that has been sitting around all season. That is typical in the Colorado continental pack but is usually settled out by this time of the year. A continental snowpack is often up side down, it's real touchy and often very scary.

    I hate the arm chair quarterbacking that ensues following events like this but just because they had all the gear doesn't mean they knew what they were doing. I'm curious if they were skiing the slope at the same time. All six were caught with only one survivor.

    If you read the Report issued by the The Colorado Avalanche Info Center that morning conditions seemed pretty unstable at best.

    Backcountry Avalanche Forecast for Vail & Summit County
    Issued: 04/20/2013 6:09 AM by Tim Brown
    Highlights
    Recent snowfall and wind drifting overloaded deeply buried weak layers and produced a cycle of large natural and human-triggered avalanches on Thursday. Moderate westerly and northwesterly winds will continue drifting snow today. Look for deep persistent slabs and fresh wind slabs on north through east to southeast aspects near and above treeline.
    The sixth Colorado avalanche-related fatality of the 2012-2013 season occurred near Vail Pass on Thursday. Our sincere condolences go out to family and friends. A CAIC accident investigation team visited the site on Friday. Preliminary information is posted on our web site.
    20/04/2013 5:32 PM by Spencer Logan: 2nd worst avalanche accident in CO since 1950. 1962, 7 residents Twin Lakes. 1987, 4 skiers Tenmile Range.
    20/04/2013 5:26 PM by Spencer Logan: Avalanche near Loveland Pass this afternoon, 6 backcountry tourers caught, 5 killed. Details limited.
    20/04/2013 2:19 PM by Spencer Logan: Large avalanche this morning Sheep Cr (north of Loveland Pass), 3-4' to ground, N aspect near treeline.
    Avalanche Danger
    The avalanche danger for the Vail-Summit zone is CONSIDERABLE (Level 3) on N-NE-E-SE aspects near and above treeline. Elsewhere, the danger is MODERATE (Level 2). Careful snowpack evaluation, cautious route-finding and conservative decision-making are essential.

    Yes it does but what is done is done. It's possible that they were skiing one by one and meeting in a "safe spot" and this monster slide propagated into their "safe spot" but it's hard saying without really knowing.

    With the avalanche danger forecasted as considerable it wasn't a day to be gang bang skiing an avalanche slope.

    Check out the pic on this link. Looks like it was a hard slab that pulled out on some serious low angle. Crazy, they probably didn't see this one happening until it was too late.

    You can travel in considerable conditions Azpilot but things can also go very wrong.

    RA, you didn't post the link but here's the CAIC report. https://avalanche.state.co.us/acc/ac...rep&acc_id=505

    Sounds like they were skinning up and triggered it from below. The crown face was 4 feet deep and 500 feet wide. Yikes.
