The Spitzer 8 $\\mu$m image reveals an elongated/filamentary infrared-dark cloud (length $\\sim$28 pc) associated with N59-North, which contains several protostars and seven ATLASGAL dust clumps at the same distance. The existence of this filament is confirmed through $^{13}$CO and NH$_3$ molecular line data in a velocity range of [95, 106] km s$^{-1}$. All dust clumps satisfy Kauffmann & Pillai's condition for MSF.
