I was back at Whitewater again yesterday. The inbounds lines off the Summit chair looked well tracked, but Jordy and I found fresh lines in Ymir bowl. The snowpack is still very thin on ridgelines and around outcrops, but it’s mid-winter powder skiing in the gullies. At upper elevations there’s a supportive crust between 10 and 30 cms down, with unconsolidated snow down to ground at lower more protected elevations. Here’s Jordy making turns down from where the the Dog Leg Chute runs into the main bowl.

The ski hill is tracked out now, but Ymir Bowl continues to have some untracked. I think the wind got in there since your day though, it was nasty all the way down, and I only found a few sets of 4-5 decent turns before hitting the next windslab trap. 😦
Some reactive windslab down low in the bowl, with decent propogation up to 20′.
