Follow the crack to the right of Hubba Bubba until it ends, and then go up the slab past 3 bolts to a belay station. This was drilled on lead by hand. All that banging on the drill really brings out the cave man in you. Fortunately technology progressed, and now there are better methods for placing bolts. As I recall, we were thinking that one of the bolts wasn't as good as the other two, but maybe they've been replaced since the late 1980s.
This is in the center of Snake Buttress between Hubba Bubba and the partially erased route called Rattler.
Gear to 3".
