Problem: new snow/slab -4-6in on top of crust from freeze thaw cycle.

As we were skier were touring, we noticed only new snow problems, that illustrated minimal connectivity. We only encountered sluff through the morning, and felt confident that there would be Minimal propagation ( we were incorrect). We did notice the crust beneath the new snow that was not binding well to the fresh layer on top, but showed minimal signs of connectivity or slab activity (again incorrect). As we skied down to around 9800- 9500 the slope averaged around 30 degrees, but on the skiers left side it increased to 35-40. One skier rode to the steeper slope, and it started to carry him. The second skier was slightly behind him and to the right quickly got carried as well. The third skier was near the crown, and was carried about 15 feet, the other 2 skiers were carried about a quarter of the slope and went over a small cliff band. Luckily everyone was fine and uninjured, we commenced a quick beacon search to make sure no one else was involved, which there wasn't. Glad everyone made it home!
