The Local Group galaxy IC 10 contains a remarkable number of Wolf-Rayet stars for a galaxy its size -- at least twice the density of such stars seen in any other Local Group galaxy -- suggesting that it is the site of ongoing starburst activity. However, until recently IC 10 has not been the subject of extensive study because of its low galactic latitude (b ~ -3(deg) ) and consequent high reddening (E(B-V) ~ 0.8). As part of a multi-wavelength study of IC 10 and its star formation activity, we have obtained deep U, B, V, and I images of IC 10 with the ARC 3.5m telescope. From these images we have constructed a map of the reddening and extinction along the line of sight to IC 10 which shows considerable variation on scales as small as 10arcsec . Based on this map, we have created reddening- and extinction-corrected images of IC 10, which we have used to analyze the galaxy's morphology at different wavelengths.
