Three stars for a good opening effort.
Just the beginner hill (the gulch) is open, better than any beginner hill at mt high or elsewhere...
Also, the terrain park is open with a few features (a low rail, and two kickers, one of which is followed by a rail, and a nice steep landing slope after.
It looks like there's a good base on bonanza too. I imagine they're just waiting to have temps to make enough snow to cover the top of Thunder so you can get there.
Also, just a side note... Are some of those snow makers new??? I don't remember the big fixed yellow ones last year. It looks like they did some upgrading and expanding over the summer.
