We present mid-infrared, moderate resolution (R\!~!600) spectra of northern hemisphere Wolf-Rayet stars of most sub-types. Helium recombination lines and dust features are observed in all of the spectra, and are used as the basis for discussion of the physical parameters of individual WR winds. The observational significance of WR phenomena in regions of intense star formation is discussed in the context of the data presented.
