At the top of the drive, just outside the park, is an extinct volcano. The upper strata flow that lies on top of the sandstone helped to preserve the rock beneath it, and so Snow Canyon itself owes its existence to this long dead giant. The basaltic aa flow is a bit tricky to navagate, so I didn't go too far up. I would have loved to go on, but my shins began to quiver in fearful anticipation. Pahoihoi would have been fun to walk on, but I'm not aware of any Pahoihoi flows extant here on the big continent. Oh well. Perhaps someday we'll make it to Hawaii and I'll get my chance. Until then, I'll just have to make due.
