Mt Adams has snow down to Pine Creek snopark, but the sledding won't be any good from the snoparks until the temperatures get above freezing. Pure ice surface in the snoparks will make it impossible to load your sled. The trails are currently brutal icy workouts that only shorter lug snowmobiles can negotiate without overheating. I never made it up the mountain but it is likely that it is powder without an icy crust up above 5000 to 6000 feet. You just have to somehow get there without stopping your overheated sled every 1/4 mile.
