Avalanche in Cold Stream

We were skiing lower angle north treed slopes prior to the incident. It was snowing hard all day and we were seeing no signs of instability between the old and new snow. Three of us in from a larger group made the decision to go to a zone that we had skied prior in the week, in much steeper avalanche terrain. We did not dig a pit, however we did preform a number of other tests, including hand pits and test slopes. There was no wind and no signs of wind loading on the slope so we decided to ski it after much discussion. We discussed safe zones and spotting for the desent and I dropped in first planning to ski cut just incase. The slope ripped on the ski cut, it was approsimately 1-ft deep and 120-ft wide and ran the entire slope. We didn't investigate further, feeling spooked and wanting to get out of there. There were a number of human factors that lead to skiing this slope that I'm aware of and trying to process.
