Description
In the right side of the southeast face of Underworld Rock, climb up the very large and wide crack system to the roof about 50 feet off the ground. Though not necessary, and medium-sized cam could be helpful until your reach the bolt below the roof. There is another bolt just over the roof, and pulling yourself up and over is the crux. Climbing is easy after this, and you should head left from the top bolt to the bolts at the highest point on Underworld Rock.
If you are going to top-tope this route, putting adirectional draw on the last bolt is a good idea.
Referred to as “Underpass” in the 2021 Edition of Bay Area Rock.
