@SKLund, I'm actually aiming to do this route as well as I've been piecing together info on it over the last couple of weeks, but not the full 32 miles of Spring Canyon to Pleasant Creek Route that was published by the magazine aforementioned. I'm aiming to just do the 17 miles or so from Grand Wash to Capitol Gorge which is what Michael Lanza and a friend of his did with Steve Howe's route beta, which I think it the section they've called the Beehive Traverse. Despite Michael's post and Backpacker publishing info about that route and beyond (courtesy of Steve which you can't fault because after all, he's the one who apparently pioneered it), I'd be willing to bet that it still sees few, if anybody else, traverse that route outside of Steve's guided trips from year to year.
Next month I'm aiming to do the Capitol Gorge-Pleasant Creek route as an overnight loop, and then hopefully fit the actual Beehive Traverse in, possibly the week after, or later this fall myself. My in-laws live in Torrey now and so since I've essentially married into that park, I'm hoping to become as familiar with at least all the non-technical areas as I can, and I think I'm just going to continue working through various sections moving southward as time and circumstances permit me to. I know there's one somewhat tricky and exposed spot to climb out of Bear Canyon and another exposed ledge just before descending down to the Tanks as you enter Capitol Gorge. I'm hoping to have time to scout out these more exposed spots near the beginning and end of the route when I'm down there next month in order to make sure I'd be comfortable enough with them myself. Steve also marked a waypoint where there is a short slot that when he and his crew had done it, they had to wade through chest high water that was unavoidable, but interestingly, Michael makes no mention of such a wader in his write up of that. I've actually created my own map in my Caltopo account using Steve's GPS track and all of his key waypoints and then made more precise adjustments with satellite imagery so that I can have all that cached and on the ready whenever I attempt it. That's a route with a handful of pour-offs that you need to know exactly where to look and go to safely bypass them.
I was selfishly hoping to be the first one to break a TR of it here, but maybe you'll beat me to it. Then again, If you don't mind company, maybe I could join you if the time you're looking at this fall overlaps with days I'll have off? My only concern with doing it in the fall as opposed to the spring is that fall is typically drier and so the many potholes throughout the washes along the way may almost all be dried up come fall, where as in Spring, it's more likely that water sources would be more abundant. Then again, Michael said in his write up that they only found water in two spots and it was April when he did it.
