Talk:List of national historic landmarks in Colorado

message: I had removed these 3 sites from the article with the explanation that they are units of the National Park System, and not National Historic Landmarks.  These are two separate programs, both operated by the National Park Service.
The 3 sites were reinstated to the article by Buaidh by reference to a PDF of an NPS list of NHLs in Colorado. The list had two appendices in which Yucca House and Hovenweep were listed, and Sand Creek indirectly referred to.
But I still don't believe that we have any references that document those 3 sites are NHLs.  The appendix in the PDF referred to by Buaidh is headed: "National Park System Units Automatically Listed in the National Register" (italics added). However, the National Register of Historic Places named in the PDF is yet a third separate program operated by the NPS. While it is closely related to the NHL program and they are frequently confused, they are not the same.  All historic National Park System units are automatically added to the National Register, as are all NHLs, but no such automatic relationship exists between National Park System units and NHLs that I can tell.  Some National Park System units are designated NHLs (Bent's Old Fort), but apparently not all.  Some National Park System units fail to meet the minimum criteria for the NHL program - reconstructions, for example (Fort Clatsop, OR, and Abraham Lincoln Birthplace, KY, pop to mind).
The inclusion of that appendix in the PDF has confused me in the past.  I have tentatively concluded that a careless clerk included the appendix in the PDF without understanding the relationship between the NHLs and the National Register.  Meanwhile, I have looked for any documentation that specifically addresses whether/when National Park System units receive NHL designation.  I have found none.  If Buaidh or anyone else can produce such documentation, I will be very interested.
I continue to believe that Yucca House, Hovenweep, and Sand Creek still need to be removed from this list (and from List of National Historic Landmarks by state).

replies: text: Absolutely correct, those are not NHLs.  However, I choose to list them and other NPS-administered areas in Colorado in a supplement at the bottom of the article, which has been thoroughly revised. doncram 17:14, 17 October 2007 (UTC)
