Today was a bluebird day in the Sierra. Several hundred feet from the ridge line of the gully I was in, the wind picked up dramatically from the north/northeast. I noticed some wind slab formation in certain exposed areas of about a depth of 15cm with no instability noted and I did not see very much wind transport happening in front of me. A quick hand pit revealed faceting crystals underneath this layer. I chose to dig a more proper pit in the shade below a tree at 10,789 feet to see a little bit more of what was going on this area. It was only 65cm deep but I was surprised to find two thin layers of pencil/knife- hard ice that I did not expect. A compression test showed a collapse at 9 taps above the first ice layer and then a collapse at 12 taps between two softer layers. Everything else to the ground appeared to bond well. No instability was noted anywhere on the ski down in the trees.
