Carbon Junction overlay *PIC*

Quite a while back there was some debate about the location of the grade at the Walmart site in Durango. Someone contacted me back channel and asked if I could do a Carbon Junction overlay. This one was a bit of a challenge since the MS aerials don't show the Walmart (Google does but I don't like their overlays). So what I did was overlayed the grade on the MS map. I then snatched the Walmart rooftop from Google and added it to the map.
Based on this overlay the Farmington grade is close to the river and is behind the Walmart buiding. Looking at the Google aerials it looks like it may have been turned into a path. Maybe someone in Durango could check it out.
The grade heading east to Chama goes through the parking lot. One of the smaller buidings on the north side of the complex does intersect the grade.
Another thing to note is the red line that I drew on the map. Is this a grade or some other feature? Hard to tell from the aerial and it doesn't line up with the valuation maps.
