Obstacle 3: Cliffs and Waterfall (Lower End of the Subway)
The last obstacle is a 30 foot cliff, which can be passed several ways. There are a couple of anchor bolts to rappel from on the left (south). To get to them, you'll have to go past the waterfall on the left. Alternatively, you can rappel off a long by the waterfall, or you can scramble down the cliff between the bolts and the waterfall.
Once you're down, you can pack your gear because you won't be needing it anymore. From here on out, it's mostly drudgery.
