Ruta 17 - Heading West on Ruta 17 Provincial, Santa Cruz, Argentina: You won't find this leg of Ruta 17 on google maps, but I assure you, it is there. It runs just north, and about parallel to the Santa Cruz river. We drove for 5 hours and never passed another car, never saw another vehicle. The landscape just rolls. On our way back, west to El Calafate, the sun set and burned light across the clouds being eroded by the streams of wind coming off the peaks of the Andes.
