As of Thursday April 17th snow was still blocking the road to Siouxon Creek at the Horse trailer parking corner at the upper trail head.  It is now 'only' about a foot and half deep.  It looks like this is the last snow blockage, since the road below that looked cleared - at least what I could see from above the blockage.  My guess is that it could be passable in a probably over a week.  The new snow expected this weekend probably won't last very long once temperatures warm back up to normal.
