[Historically, finding the distances to objects outside the Solar System has been one of astronomy’s most difficult tasks. This is especially true of things like interstellar clouds where luminosity distances play no role. In this chapter we describe some of the techniques that have been applied over the years to obtaining the distances to molecular clouds. In particular we focus on high-latitude molecular clouds to illustrate the efficacy of Wolf diagrams, spectroscopic, and photometric techniques. We also discuss the asymmetry in the high-latitude molecular cloud population with respect to the northern and southern Galactic hemispheres and the possibility that some high-latitude molecular clouds may be at the disk/halo interface.]
