The End of an Era...We are Shutting Down the Messageboard

We have started a Discord server and hope that you all will join us on there. Technology has changed over the years and maintaining the messageboard has become somewhat of a pain in the butt and Discord offers many features for users, the main one being a very polished mobile app.

Utah's snow quality and temps are more consistent than Colorado's. We get a lot of temperature fluctuation at different elevations, and when you combine that with snowfall, you can get a lot of different types of layers in the snow. There's also a lot more wind out here, which adds to the windloading on different aspects.

The snowpack in LCC/BCC is pretty much always deeper than CO's combined with UT's more moderate temps cause there to be a less severe temperature gradient in the snowpack. A higher temp gradient causes faceting and deeper instabilities which is what causes avalanches.

So even if it's not and out right thaw and refreeze, extremes up and down still below freezing point add a weak layer -- and that area of utah has a more consistent temp. pattern?
Definately a LOT of wind in CO high country
I need to reread Tremper -- better yet I'm already planning on timing a trip around an Avy I course next year; only like $175 at cooper
anyway glad some of you are still harvesting the awesomeness (KD let me know if you here of something good on the Icelantic Nomads -- price I mean, I know they are good)

(in reality, that doesn't really matter much when it comes to stability)
It does to an extent. I believe the rule is a temp gradient more than 2.5 degrees F per 10 inches of snow depth causes faceting in the pack, but I could be mistaken. A snow covered ground remains pretty much at the freezing point while snow insulates it. So a "warm" ground covered by 50" of snow with air temps at zero or below zero will allow the formation of faceted sugary snow. Reading the avvy report every day I frequently saw warnings about shallow snow areas which serve as trigger points because the snow is less stable. My own BC observations also support the idea--most of the naturals I saw in the BC originated in shallow areas or below cliffs. Often just below the crown line there would be a big area of "salt and pepper" snow where the pack was obviously shallow.

UT is lower elevation than CO so there is less wind and the temps are not as harsh. Theres a reason people call Breck Breckenfridge
