  A real tunneling solution is an instanton for the Hartle-Hawking path
integral with vanishing extrinsic curvature (vanishing ``momentum'') at the
boundary. Since the final momentum is fixed, its conjugate cannot be specified
freely; consequently, such an instanton will contribute to the wave function at
only one or a few isolated spatial geometries. I show that these geometries are
the extrema of the Hartle-Hawking wave function in the semiclassical
approximation, and provide some evidence that with a suitable choice of time
parameter, these extrema are the maxima of the wave function at a fixed time.
