Trinidad, CO appears to be "Opening Soon" on the Tesla "Today" map. I exchanged e-mails with the head of the Building Department in Trinidad, and he told me that there is a permit application from Tesla that is being reviewed. The location will be:
9700 Santa Fe Trail
Trinidad, CO 81082 - Google Maps
185 miles is a little far from Lone Tree, but it looks like there is another Supercharger on the "2015" map in Pueblo. That will make the distances much more reasonable.
South of there, there will be Superchargers in Las Vegas, NM; Albuquerque, NM; and Santa Rosa, NM.
