Hi, Darren,
As kids say on the internet, "KEWL!" I think most of the flowlines are
strain lines or stretch
lines that date to the plastic phase, but there's one near the top of the
object that is a true
"channel." Notice how many pits are elongated in the direction of the lines
that cross them? Streeeetch!
Really nice picture. If it had a black backround, I say, "Which moon of
Saturn is that, now?"
