An uber classic, the Undertow boulder sits uphill from the Fight Club/Mini Me region and can be easily accessed either by the old roadside trail or from the Illegal Parking Lot, taking a right at Azians Slab and heading downhill past the Chockstone Highball.
Undertow has a V-manageable sit start, steep fun hard moves slapping into the arete and 5.10+/- top-out. Variants are abound on this corner, sit starting elsewhere and coming into Undertow, and moving from Undertows start to other problems.
Undertow Boulder also has 2 classic problems. To Undertows climbers right there is a highball face with an uberstout sit start and to Undertows left there is a line running up the left flank of Undertow with Mickey Mantle Boulder at your back.
