I was at the north site yesterday. The snow is basically melted off, leaving some coverage in that little pistol area off to the left as you walk in, and a swampy puddle 100 yards out in front of the hill. Mostly dry, though -- even dry enough for prone.
It seemed kinda messy. A lot of shotgun hulls and some brass were laying around. I'm guessing they were hidden under the snow and all the unrecovered mess from snowy winter shooting has emerged. I picked up a bunch of stuff, but there's a lot more there.
