The ANGST data set is providing an unprecedented wealth of high quality data that allows us to construct both the global and recent star formation histories (SFHs) of numerous galaxies in the Local Volume. As an initial example of our work, I will present the global and spatially resolved recent SFH of DDO 6, a Dwarf Irregular galaxy located in the Sculptor Filament. The SFH of DDO 6 shows an early period of star formation from 12-14 Gyrs ago followed by a period of relative quiescence until 1 Gyr ago. Within the last 500 Myrs, I will show how the regions of star formation propagate throughout the galaxy, which provides insight into the mechanisms that trigger star formation. The same type of analysis will be performed on all the dwarf galaxies in the ANGST domain, which will provide unique insight into recent star formation processes and galaxy evolution.
