Column density maps derived from 60 and 100 micron IRAS images of several regions of low mass star formation are presented. These maps contain as many as 3 times 10(5) resolution elements and display very complex and diverse patterns. The multifractal scaling of this structure is studied through the f(alpha ) spectrum of singularities, a tool commonly used in non-linear dynamics for characterizing complex images and time series. All subregions with adequate data were found to exhibit well-defined multifractal scaling. The shape of the f(alpha ) spectum was found to vary radically from region to region implying that the column density structures do not form a single `universality' class, in contrast to indications for incompressible turbulence. These results are intriguing in light of the apparently universal perimeter-area scaling exponents found for many of the same regions.
