This is as high as we got on the 4×4 track which leads past El Muerto to Refugio Tejos on Ojos del Salado. We climbed Muerto in the morning and decided to then cycle a bit further up the road to see where we reached. People have continued with bikes all the way to the hut at about 5800m (and further), but with no plan to climb the highest volcano in the world from the Chilean side, we soon turned back when the weather closed in.
