The X-ray enhancement associated with the North Polar Spur (Radio Loop I) was observed by a soft X-ray instrument on OSO 8 during August 1975. This paper presents image-processed maps of the region scanned, a detailed analysis of the X-ray data, and interpretations of the data in terms of supernova remnant models. If the neutral hydrogen ridge, radio continuum ridge, and X-ray emission ridge are all associated, then they cannot all be fitted by a single supernova remnant model because they require different energies of explosion. A reheated supernova remnant model does appear compatible with all the available observations.
