I doubt that either of those national parks were visited by AR20. The simple reason is distance. It is 800 km from San Luis, next to de las Quijadas National Park and from National Park Talampaya to Buenos Aires there is a distance of 1,200 kms (driving through the 9th highway from Pan American ramal Escobar to Cordoba, Carlos Paz Highway, Route 38 up to Patquía, route 150 to get to the Talampaya National Park and route 76. From the city of La Rioja, take Route 38 to Patquía then continue along the 150).
That's a bit much, even if all teams were routed that way from Cafayete on the return to Buenos Aires, which would add several hundred km.
I wish I had an alternative hypothesis on which rock formations are in the photos in question. I am working on it but don't have any right now.
