I'm glad someone could use the updates so soon. This was an extremely ambitious project that Steve undertook. I thought I could throw in my two cents worth where I actually had some ideas about where things were. The trouble with any maps of historical things is that roads and rivers move so landmarks that were good when a map is/was published may be wrong later. This is one issue with Tracking Ghost Railroads in Colorado as it pertains to the RGS. Highway 145 and some other roads have moved since its publication.
