The initial overhang on this route is much more imposing than the word "bulge" suggests, but "Beatle Brow Roof" lacks poetry. Either way, it's a great pitch. Historically rated 5.9+, the latest version of the Williams guide calls it 10-, which I think is accurate considering the sustained overhanging climbing above the roof.
The access trail for Beatle Brow Bulge is about an 8-min. walk from the Uberfall, or a 4-min. walk from where the East Trapps Connector Trail meets the carriage road. At the cliff, head uphill to the right, past the huge right-facing corner of Asphodel.
Begin about 70 feet right of Asphodel, where the trail levels off. Climb easy rock up to the roof, passing a vertically-placed pin about halfway up the face. Climb through the well-protected roof at a short left-facing corner/flake, and then straight up the overhanging face above on good holds. (Be aware that Blueberry Wine, a 5.11, goes through the roof at a similar looking left-facing corner a few feet to the right of BBB.)
Above the overhanging section is a ledge at which the angle eases and the rock becomes dirtier. There is a rap station at a tree about 30 feet above the ledge, from which a top-rope can be set up with a 70M rope. To rappel from there using a single 60, go to an intermediate station off to climber's right.
There is a second pitch to the top, of lesser quality and difficulty, which angles up right to a left-facing corner.
