Start in just about the middle of the wall. Climb over another small bulge and follow the middle crack seam to the finish. Exit by traversing left and down climbing to safety!! Best line on the wall!! Should not be missed.
Many variations can be done from the middle point in the wall that are really enjoyable. Go give it a try!!!
From the 1st parking lot follow the Sisters Trail for a few hundred yards or until you come to the Ponderosa Trail junction just below and to the EAST of the "Brothers Lookout" formation. Turn west (Left) onto the Ponderosa Trail for about 30-50 yards before you began to head NORTH (right) up the steeping slope. Try to stay as EAST as you can so you enter the 2nd Tier gully at a gradual pace. The "Brother-In-Law Wall" is located up (West) and right past an obvious mini cave called the "Brothers Under Belly Cave." Walk about 20 feet past the cave and the "Brother-In-Law Wall will come into view. Enjoy
