Was up there yesterday, wouldn't attempt without a high clearance 4WD vehicle. There is high snow and very deep puddles on the way in. Rock conditions were fantastic though if you can make it in/out. I did just fine on the way in, but managed to get myself stuck once on the way out. You'll have the whole place to yourself though!
Edit: Also I'd like to note that the southern parking area is currently blocked by a fallen tree. Not a big deal to walk the rest of the way in to though. Only about 1-200 yards from the parking area proper. Cheers!
