The detailed velocity field of the ionized hydrogen has been observed between l = 301 and l = 324 as part of an H Survey of the southern Milky Way. Analysis of the H profiles shows six different velocity components. These H observations, combined with multiwavelength and stellar data, are used to find the most probable distances of the different gas layers.
