There's too much uncertainty. Let me point out a couple of examples here.
Exhibit A: the Toots To Boot avalanche from Monday - A very experienced party skied on low thirty-degree terrain and it wasn't until the second person on the slope skied that it propagated back up and across the landscape to where the terrain reached the 44° steep headwall, pulling the whole thing down 300' wide. Standing just off to the side, the first skier watched the slide roar down, coming within 10' feet from where he was standing.
Exhibit B: Note the photo above (in Recent Activity) of Wilson Chutes shoulder. The Wilson Chutes and apron remain intact as skiers center punch the line while the shoulder apparently had more snow and wind than it could handle.
There is a great deal of spatial variability across the range. Those skiing and riding the steepest lines in the upper reaches of the Cottonwoods that take their game to the steep terrain of Mill Creek, Mt Aire and Lambs, the Sessions, areas along the PC ridgeline and the Wasatch back of Snake Creek, etc may not find things as, shall we say, forgiving. Similarly, snow tests in our suspect terrain elicits various and sometimes conflicting results. But it all has faceted snow and it has all seen significant wind and storm loading in the past week. Don't try to outsmart the avalanche. As the famed Swiss avalanche pioneer Andre Roch warned years ago, "The avalanche does not know that you are the expert."
When presented with great uncertainty, one must allow for a greater margin for error. What does this mean?
- For those with Low Risk Tolerance, it means avoiding being on or beneath and steep slopes facing west to north to even southeast.
- For those with High Risk Tolerance (and apologies to Chuck Yeager), it means always leaving yourself a way out. If you choose a slope that doesn't share the same opinion of stability as you do, make sure the slope offers a place to run or hide, or at the very least, a cleaner runout that doesn't result in a deep burial or one where you're strained through trees or over cliffbands.
