Poor Snowpack Structure

We skinned/skied through a lower-angle burn area that was adjacent to a major slide path with a steep start zone that ran during the February cycle, and got a couple of whoomphs and cracks on the ridge, which we stuck to before dropping down lower-angle shots. We did a couple of hand pits and saw that the new snow didn't bond very well to the old. But due to a lack of wind at that elevation/in that kind of shelter there wasn't much of a slab. All of this was around the 8-9k range, well below the summit that undoubtedly had more wind. Below 8k there was better bonding, and we didn't go much above 9k due to poor viz. With my probe I was only able to go down 4 feet to the ground at around 9k, with the assumed PWL near the base, which indicated to me that since the snowpack wasn't as fat there as in the Central Wasatch - where we've mostly been playing lately - the PWL may still be in play? At the end of the day as we dropped into the low elevation exit gully we had to be conscientious about very small wet slides even north facing due to heating.
