2 tracks in from the peak of Milli and out back to Milli lift area. dimensions and trigger are a guess because it was still snowing enough to have restricted vis from solitude. 1 skier track appeared to trigger slide and possible catch / carry due to not being able to see that track near the slide area. Other skier appeared to skirt slide area down to the point where 1st skier track is visible again. Both tracks head back toward the resort. The slide ran quite a bit longer across the lower angle than most of the naturals that come off that zone. ~800' vertical
