  The initial results of the Deep Lens Survey (http://dls.bell-labs.com) to
identify possible brown dwarfs and extremely metal poor red halo subdwarfs near
the hydrogen burning limit are presented. Individual deep CCD high galactic
latitude survey fields appear to offer a low probability of discovering field
BD's, but taken collectively offer an opportunity to begin addressing questions
regarding the scale height and distribution of these objects. In all
likelihood, the very depth of such surveys will greatly increase our knowledge
of the coolest extreme halo objects, which currently are known in far fewer
numbers than T dwarfs. Ultimately, the large volume surveyed by the Large
Synoptic Survey Telescope will identify vast numbers of such objects, providing
a more complete picture of their spatial distribution.
