Examination of nearly 1,000 detailed HI maps at hundreds of velocities has lead to the discovery that the morphologies of galactic HI and WMAP ILC structure in certain areas of sky bounded by latitudes b = 30° & 70° are closely related. To date, some 200 closely associate pairs of features have been identified and some of the most informative cases will be displayed and discussed in the context of what they reveal about interstellar phenomena. The pattern emerging in the data suggests that in directions where two HI features (usually segments of filaments) are interacting, physical processes at their interface give rise to the weak, small-scale structure in the continuum radiation observed by WMAP (and, by implication, COBE as well). If, on the other hand, all the apparent associations are to be attributed to chance one must ask whether we are so sure about interstellar physics that we can safely ignore the phenomenon in order to draw far-reaching cosmological conclusions from the WMAP data.
