A crew went up there on Saturday - ran Richochet thru the Plunge. You can drive all the way back to Eight mile. At that point you will look straight up the road into one of the biggest ugliest mudslide messes you ever did see. It goes for several hundred yards up the road- you've probably seen the pics. Lots of debris and some big boulders at the head of the sh^tpile. You won't be driving any ATVs thru or on it.
On Friday I briefly spoke with a ranger at the Ltown office and she said that it would be a couple weeks, and sounded confident that the road will reopen sometime soon this Spring. There are people who live year round back up in those woods so its a major inconvience for them and theres plenty of pressure building to see the mess cleared from rec enthusiast of all stripes.
It probably isn't worth the effort to do the hike in. You need at least 5k at Pesh for the upper; and at that point other options are available.
The Middle stretch of Icicle (8m- plunge) is in primo condition except for one branch sticking into a boulderdrop ledge just above the plunge (visible from road), and that goes but the line is narrow.
As far as whether the upper run has been affected by the slide... that remains unknown, but I'll hazard the guess that it's all good up there. The slide is way downstream from the classic Roadside/Limbo stretch of water... but as always, new wood could be an issue to report. We'll see... hopefully by the end of April.
