  FA - David Wood, Dennis Erik Strom, 11/94
175a2. Aqua Cruda 5.10d  5x, thin corner system (gear), left side
  of a bulge, to a short headwall/streak. (just left of Edge of Sundown)
  FA - Dennis Erik Strom, David Wood, 3/96

  runout up headwall to last bolt

175d. The Agony of Defeat 5.10a  3rd Knuckle, a bit loose between 4th & 5th
  bolts.  Knobs below first bolt are loose -- don't pull out on them.
  On the first ascent, a knob blew while Dennis was bouldering out the moves
  to the first bolt, and he took a cartwheeling tumble down the slope, like
  the infamous Yugoslavian ski jumper on ABC's Wide World of Sports!
  FA - Dennis Erik Strom, David Wood, 1/94
Note: these routes are often closed during bird nesting season, so the best time to climb them is October-December.
