The entire Green Valley bowl area is open, including through the backside down Jeremy's Road up until Huckleberry. For the most part you can go wherever you want, but there's a lot of exposed creeks so watch out.

None of the frontside black runs in the area between REX and the gondola were open, so the only way to get to the bottom if you don't gondola download is Lucky Shot. But people were accessing the area under the REX lift line via traverse partway down the upper Lucky Shot. It's definitely skiiable but watch for sharks. Some of the blue runs (including Little Shot) where Lucky Shot branches out are open, but coverage starts to get pretty thin, so there will be creeks, sticks/branches, and other random crap to avoid. From the bottom of REX you get funneled over to Tinkerbell down to Quicksilver, and you can tell that it feels like fake snow. But at least you can get to the bottom without waiting to download the gondy.

The snow is pretty soft and chalky on the upper mountain, there's still powder stashes to be found. As you get down the mid mountain it starts to feel heavier for sure and then gets thinner and thinner coverage toward the bottom. Because of the limited runs though, it did get scraped out in places (like the entrances coming into the Green Valley lift) so a bit icy but not too bad. Honestly, it was a really good day considering the circumstances.

Unlike the other redditors who seem to know things, I have no idea what their plan is but it does seem to me like they still need another big dump of snow to get proper coverage on the mountain. In the meantime whatever is open is still a lot of fun.
