Crux is down low traversing out and up into a finger crack. About 20' from the start.
Follow the coast of South America all the way up. Can drouble rap (2 ropes) from Amazon Woman anchors (barely). Tie a knot in the loose end and make sure the not by the chains is a good 5-10' from the chains, otherwise you'll never be able to pull the ropes due to the knot friction going over the top of the continent.
Couple large pieces are nice (#3 camalot or larger). Few small to protect the crux move out the lieback and into the finger crack.
