Bob Dylan is one of two adjacent cracks on the far left of the Twin Cracks section of the Sunshine Wall. The guidebook we have gives it a 5.10b rating but that seemed way generous...feels easier than Air Guitar. Start in a thin hands crack (#.75-1 Camalots) and traverse slightly left near the top. Gear anchor at the top. Watch for slightly flakey rock at the top (helmet esp. for belayer).
Route starts about 25 feet (of 3rd class choss) above the trail. Just to its left is Welcome To Vantage crack. There's some bolted arete 10 feet further left.
Standard rack to 3". Lower part (bulk) of route will take #0.75 to #1 Camalots.
