We combine both new and archival Green Bank Telescope observations to construct a spectroscopically resolved HI~21-cm map of this entire complex at a $17.1\\lesssim\\log{\\left({N_{\\rm HI},\\,1\\sigma}/{\\rm cm}^{-2}\\right)}\\lesssim17.9$ sensitivity for a ${\\rm FWHM}=20~{\\rm km}\\,{\\rm s}^{-1}$ line and $\\Delta\\theta=9.1\\,{\\rm arcmins}$ or $17\\lesssim\\Delta d_{\\theta}\\lesssim30~\\rm pc$ spatial resolution.
