We present the initial results of a Hubble Space Telescope/Advanced Camera for Surveys snapshot survey of 16 nearby, edge-on, late-type galaxies covering a range in distance from 2 to 19 Mpc. The images of these galaxies show significant resolved stellar populations. We derive F606W and F814W photometry for more than 1.2 million stars and present color-magnitude diagrams that show a mixture of young, intermediate, and old stars in each galaxy. In one of the fields we serendipitously detect stars from the Large Magellanic Cloud. We also identify a candidate young dwarf galaxy lying similar to 2 kpc above the plane of NGC 4631. For the nearest six galaxies, we derive tip of the red giant branch distances and demonstrate that these galaxies fall on the K-band Tully-Fisher relation established in clusters. From the color of the red giant branch, we also find evidence that these galaxies possess a metal-poor thick-disk or halo population.
