The 100 kT LANNDD liquid Argon TPC is well matched to these goals. We describe the progress in the R&D program for the detector as well as the possible location in an underground laboratory in the USA called DUSEL.13 pages, 6 figures, invited talk at the XI Neutrino Telescope Conference, February 2005, Venice, ItalyAstrophysicstext
