Our party of 2 boot packed up a chute on the east face of mount baldy, and performed a compression and ECT test at the bottom of the chute, both showing good conditions, with nice right side up snow. We noticed quite a bit of wind loading at the top of the chute, and performed a defensive ski cut to test for wind slabs. The wind slab slid the full length of the chute. Both in party were unharmed.
