We present HST/WFPC2 imaging of the nearby (D=3.9±0.2 Mpc) dwarf starburst galaxy NGC 625. This system is host to a young, massive star formation region, comparable in Hα luminosity to 30 Doradus in the LMC. Hα and Hβ imaging reveals substantial and variable extinction (AV = 0.0-0.6 mags) within the major star formation regions. Using V and I imaging and a new modeling technique, we account for this differential extinction and derive a recent (< 100 Myr) star formation history in which an elevated but declining star formation rate has been present in the disk for this entire period. This is at odds with the presence of spectroscopic Wolf-Rayet (W-R) features in the major star formation region which imply a short duration (≤ 5 Myr) for the recent starburst. This suggests that starbursts displaying W-R features are not necessarily all of a short duration. These results have important implications for distant systems where a study of the resolved stellar population is unavailable.
