Our group of 3 ascended to the top of Highline in Mineral Fork. We discussed the strong westerly winds that were loading the NE-facing slopes as we got to the ridge. To the lookers left in the video, we didn't see any signs of a wind slab. Rider 1 dropped in to the lookers left, did a ski cut, and had no results. Rider 2 dropped in along the same path as Rider 1 without any results either. Rider 3 decided to go lookers right where the terrain was steeper and had obvious signs of wind loading. Rider 3 dropped in to do a ski cut and immediately released a soft wind slab that ran a couple hundred feet down the slope.
