Our spatially complete search for low mass members of the Pleiades using 2MASS and USNO proper motions has revealed hundreds of new candidate members down to 0.1 {M}sun. This extensive survey has allowed us to determine the mass distribution in the cluster out to the tidal radius. We present a precise estimate of the stellar mass, including a correction for unresolved binaries, and discuss the radial distribution of low mass stars. We also characterize the highly elliptical projected structure of the halo. These results demonstrate the feasibility of studying the dynamical properties of nearby open star clusters using digital sky surveys. This presentation makes use of data products from the Two Micron All Sky Survey, which is a joint project of the University of Massachusetts and the Infrared Processing and Analysis Center, funded by the National Aeronautics and Space Administration and the National Science Foundation.
