  Mergers and tidal interactions between massive galaxies and their dwarf
satellites are a fundamental prediction of the Lambda-Cold Dark Matter
cosmology. These events are thought to influence galaxy evolution throughout
cosmic history and to provide important observational diagnostics of structure
formation. Stellar streams in the Local Group are spectacular evidence for
satellite disruption at the present day. However, constructing a significant
sample of tidal streams beyond our immediate cosmic neighborhood has proven a
daunting observational challenge and their potential for deepening our
understanding of galaxy formation has yet to be realized. Over the last decade,
the Stellar Tidal Stream Survey has obtained deep, wide-field images of nearby
Milky-Way analog galaxies with a network of robotic amateur telescopes,
revealing for the first time an assortment of large-scale tidal structures in
their halos. I discuss the main results of this project and future plans for
performing dynamical studies of the discovered streams.
