This from a friend who was out in the West Castle Valley, downstream from the old minimum security camp and Castle Mountain Resort, on February 25: 

today three of us skied to Castle River Falls today via the cattle corrals on the West Castle Road.  The
conditions where pretty good considering the lack of snow...we only had to
walk over dirt a couple of times and on the grass a few times.  It was fun
to go together and have lunch at the falls.  We walked out onto the beaver
dam ponds and over to the renewed dam.  If you are considering this trip we
took 4 hours round trip with breaks, chats and lunch.  A quick trip could be
done in 2.5 - 3 hours.

Otherwise, I think the snow is going fast on the trails, turns to slush by late morning, and lots of bare patches. We need snow.
