We propose to use 'Alopeke and Zorro to complete our survey of 1200 of the nearest M dwarfs to reveal stellar companions at separations on Solar System scales. Speckle imaging on the Gemini telescopes permits the detection of companions with separations smaller than the Sun to Mercury for M dwarfs within 25 pc. The resulting portrait of single and multiple M-dwarf systems will constrain models of binary star formation processes for the most common stars in the Galaxy. Ultimately, we will determine the typical separations and mass ratios of M-dwarf multiple systems and which stars orbit one another in such configurations that thwart the formation of planets.
