We present a new set of high resolution dust extinction maps of the nearbyand essentially starless Pipe Nebula molecular cloud. The maps were constructedfrom a concerted deep near-infrared imaging survey with the ESO-VLT, ESO-NTT,CAHA 3.5m telescopes, and 2MASS data. The new maps have a resolution threetimes higher than the previous extinction map of this cloud by Lombardi et al.(2006) and are able to resolve structure down to 2600 AU. We detect 244significant extinction peaks across the cloud. These peaks have masses between0.1 and 18.4 M_sun, diameters between 1.2 and 5.7e4 AU (0.06 and 0.28 pc), andmean densities of about 1e4 cm${^-3}$, all in good agreement with previousresults. From the analysis of the Mean Surface Density of Companions we find awell defined scale near 1.4e4 AU below which we detect a significant decreasein structure of the cloud. This scale is smaller than the Jeans Lengthcalculated from the mean density of the peaks. The surface density of peaks isnot uniform but instead it displays clustering. Extinction peaks in the PipeNebula appear to have a spatial distribution similar to the stars in Taurus,suggesting that the spatial distribution of stars evolves directly from theprimordial spatial distribution of high density material.
