Triggered a small wind slab in the couloir lookers left of the Whipple. We booted up a few hundred feet and noticed these small wind slabs on the sides of the couloir. We also noticed some transport going on up high. We decided to turn around maybe half way up and a few turns down triggered a small slide. I think they were piles of spindrift that spilled down the sides of the chute and formed these slabs overnight. It looked like someone had skied this run the day before as well. Some of their tracks were obscured by the wind.
