It's been a while. We ran it without a guide or prior knowledge, we kept a heads up but the Vs were obvious... we probably got out and looked when uncertain. If I remember correctly, the first two portages are on the left and the last is on the right. That said, when I ran it the Moist Slot kind of snuck up on us, look for the bridge I think. The others were more obvious.
I portaged all 3, but some chose to run the 1st and last V. The middle one looks gnarly.
