Follow the Climber Access trail as described on the Staunton Rocks page. From the Meadow Dome, head west. Go past the Bombardier Dome and the Whistle Pig, and look for the obvious large dome on your right (signed "Ranch Hand Climbing").
Per Bill Lawry: the descent is via a moderate downclimb and then a nice path down the north side (i.e., the skier's left side) of the formation.
