ABSTRACT: I will review efforts to infer the amount and spatial
distribution of dark matter within the Milky Way's dwarf spheroidal
satellites. I will show first results from a large (Magellan/M2FS)
spectroscopic survey targeting ten thousand stars within the Fornax
dSph. Finally I will present results from fitting flexible surface
brightness models to the known dSphs, revealing surprising structural
diversity within the dSph population.
