Jon Ley’s Plhumf.com website is almost as old school as mine but I needed to look nearly nowhere else. His 2006 trip fits exactly my idea for this traverse and I’ll actually be following his footsteps as long as they haven’t been erased by some new lava flow.
Andrew Skurka followed a different route. I’ve visited his website often in search of reassurance about gear and hiking pace. Due to my limited time window, I’ll need to fastpack close to Skurka level so it’s good to know it can be done. Now I only need to find out if I can do it.
Many thanks to both Jon and Andrew for the excellent info. It really helped.
