Established skin track to Source Lake. Toured up directly from Lake to Pineapple Basin and up to Pineapple Pass.

Weather: sunny with very thin clouds
Snowpack: 6-12" of powder in the shaded regions, but 2-3" of sometimes punchy sun crust over powder anywhere that gets decent solar input, i.e., all but N aspects
Area Description: Pineapple Basin
Avalanches: Small to medium-sized snow clumps - not quite cornices per se - dropping from ridgeline to looker's right of Pineapple Basin. Activity started immediately after the morning sun hit the top of the ridge W/NW of The Tooth and continued throughout the day. Evidence of larger instability in the days since the mid-week storm, including numerous areas where small wet-loose slides have been kicked off by snow sliding of ridge-tops. IMO, it would be wise to avoid travel right underneath such features.
