I actually rode to the peak just west of Haystack Mountain, just to the South of Sultan and the Blue Mountain Ridge but  I can report that the recent warm fronts have washed the snows away below 3500'. I summited (4100') and there was only 6 inches up there. The climb west of Haystack was a rough, 3900' vertical, but at the top you have views all around. It was a fulfilling ride in between the storms.  Beautiful sunrise before the ride as I drove over the Skykomish. Track and Pics here. Enjoy!
