Getting gear before the step across. There is a good green Alien up and left from Chuck that TRs the step across for both the leader and the second. The second can remove the Alien after stepping across.
When you get here, the crack to the left looks impossibly far, but if you move up the right crack and reach diagonally down, it's within reach (for most people). Do the math... The shortest distance between 2 parallel lines (the 2 cracks are close to parallel) is the perpendicular between the lines. This means you need to reach diagonally down to the left crack.
