Through a series of spectroscopic and polarimetric observations spanning the photosphere and chromosphere, we diagnose the physical and magnetic structure about sunspots. The relevant data were obtained with the HAO Advanced Stokes Polarimeter in conjunction with the NSO Dunn Solar Telescope's horizontal Littrow spectrograph and the UBF filter, using the spectral lines: FeI λ λ 6301.5, 5320.5 Å, Hα , and CaII 3933.6 Å. We examine the dynamic character of evolving active region filaments and examine the physical characteristics that influence these structures from the photosphere though the upper chromosphere. We characterize the atmospheric structures about sunspots in the presence of magnetic null points and twisted magnetic fields. Signatures of magnetic reconnection - the spectral ``chromospheric red-shift spur" will be demonstrated.
