We checked out the trees at Gin for you. If you're into adventure skinning, the entire trail is indeed skinnable. If you have long legs, you can even cross all the creeks without taking your skis off. About half a foot of snow under tree cover starting at the Hanging Lake trailhead sign, which quickly became several meters of fairly wet powder. Trail-breaking was tough. Turned around at Hanging Lake due to high winds and full white-out conditions, but the boulder field offered a nice run, if you kept your eyes peeled for holes. Snow near the lake was much drier, and very wind affected in some places. No avalanche signs observed, but didn't stick around long. The ski out was not super pleasant with no base, but it went. Walked the final couple hundred meters near the bottom to the large trailhead sign, then skis on again to exit via the resort. Honestly, the conditions were better than expected for the time of year. Should be solid in a couple weeks, if the winter weather holds.
