Pyroclastic, Revisited

I've been meaning to publish the pattern for Pyroclastic with the charts for the arch shaping since the copyright reverted back to me last year.  Well, I finally got around to it. The pattern is available in my Ravelry shop. 

I've clarified the reason for the marker placement.  If you have thought about knitting Pryoclastic but were confused by the written directions, this version should eliminate all doubts about what exactly is going on with the arch shaping.  I also added some other yarn suggestions. 

The sock in the photo is knit in Lorna's Laces Shepard Sock Solid Pond Blue, which is now available in 100 gram skeins.
