the associated sites.
The "Status" of these "Associated sites" is rather strange. I see that reference numbers of the list of different locations on the UNESCO Web site goes from 001 to 137 -and presumably you covered all of these. Yet the description ALSO clearly states "The Qhapac Ñan, Andean Road System includes 273 component sites spread over more than 6,000 km that were selected to highlight the social, political, architectural and engineering achievements of the network, along with its associated infrastructure for trade, accommodation and storage, as well as sites of religious significance."
So - which is it - 137 or 273?? To complicate matters further I note that Els has stated in the "location" that there are 291 locations -sourced from the AB evaluation!!! In fact the AB evaluation also states
"Qhapaq Ñan. However, ICOMOS considered that these may not be justified for all 291 serial components. Following additional information exchanges with the States Parties at the request of ICOMOS, ICOMOS considers that 273 serial components clearly and discernibly contribute towards the proposed Outstanding Universal Value of the property"
- so this Web site's "number of locations" for the Qapac Nan needs reducing Els - and a connection for reduction during nomination process! (The AB lists the 18 reduced sites of which 9 are segments of road and 9 are "associated" sites - they are all in Peru and Ecuador but don't include the above site near Cotopaxi. As far as I can see, only the segments containing the 9 removed associated sites are given )
A problem for you, Meltwaterfalls, is that I don't think you are going to find an easily accessible list of the grid references of the other sites!
I have just checked the UNESCO map and it is only populated with the sites given a UNESCO reference number (as opposed to the Nomination ref number). The "associated site" I referred to near Cotopaxi (South of Quito) is NOT shown
