If even a central tiny core of Smokey Hollow had survived you could give it the historic brushing up treatment, add a welcoming arch with the name and then you’ve established visual context. Really, Glenwood South and Power House square are commercial components to the greater smokey hollow area. The Google/518 west building was a back-in Southern Railway passenger (later freight only) terminal. From there to the roundhouse was the district proper. The Company Store for Southern is the building Raleigh Wine is in. The powerhouse is located where it is for dumping coal easily. Some of Smokey Hollow’s smoke came from up in this area. Maybe that could be Smokey Hollow Hill.
