The mass hierarchy of neutrinos is not yet resolved, and the question of
CP violation by neutrinos is still a complete unknown. To address these
questions a long baseline experiment from FNAL to the new Deep Underground
Science and Engineering Lab (DUSEL) in South Dakota is being planned. The
massive detectors needed for this experiment will also extend the search
for proton decay and be used to look for the diffuse neutrino flux
expected from supernovae at cosmological distances.
