The posted signs are a "no parking between arrows" signs and the arrows end a couple hundred feet down hill from the east crag. So, you can park on the shoulder down there. It isn't bad to do if you are going to climb at the East Crag.
Loc: in your backyard
Drove by Sunday. Forget parking (Lot was full and then some as only ½ of it was plowed). As mentioned by strat you need to walk a little but most of all bring a BIG shovel. You need to carve out a hole out of the 4 snow bank to park.
