Haven't posted here, but have commented in the past. Bumps skiing very well. No significant obs, as everything was fairly well bonded and we stuck to supported terrain. Went as far as Cowboy, Additt, Russet Ridge/Addit Lakes. South aspects were showing pinwheeling (esp. Russet Ridge south aspect cliffs). We avoided cornices with consequence and convexity's and had a great day of skiing in boot top wind transported and fresh snow. 

Even a mid-course correction down Cowboy to avoid "the" convexity, showed no shooting cracks of whoompfs despite obvious wind-loading. We still avoided for good measure. 

That said, Singing Pass sucks hard right now. Rock hard and frozen. If you don't trust your edges or your ability to edge or control your speed, you will not have an enjoyable time. We are both reasonably skilled skiers and still found it hard to have fun. Saw a couple folks who were rather "gripped" about it all. Choose Singing Pass with care and knowledge of your parties compassion for crap.

Beautiful day in Marriott Basin today. Some solar effect on steep south facing. A few windslabs to sz1.5 failing near ridgetops in unskiable terrain. 15cm of light facets over mfcr in alpine to 1900m on N asp and higher on S asp sluffing easily on moderately steep terrain. -18C at trailhead this a.m.
On course on spearhead glacier and watched this size 1.5-2 get skier triggered above the col between spearhead glacier and vista bowl. No one caught in it, but it tracked right past a group on the shoulder - moderate avalanche conditions doesn’t mean open season!!!

Skier triggered avalanche yesterday.                                                                Micheal Neal Image
