There are plenty of Cottonwood pass permits available. I think the "W" indicates there is no quota at this time and all you do is walk in and request one. Later in the summer (Fri, June 27) they have reservable permits. But of the reservable days, the first fully reserved date is July 24. And that is only the 60% reservable. 40% (16 permits) area held back and available for walk-in requests starting the day before the entry date.
