The climate has changed dramatically as we've travelled north. The nights are still cold or at least cool, but daytime temperatures can exceed 40 degrees C in the sun, and it's often above 30 degrees C even at speed. Most of the days ride was on ripio and hard-pack, with an occasional section of pavement.
Along one section of ripio, we were flagged down by a cyclist looking for water. He had misjudged the heat and distance and was running out of drinking water. We were carrying two litres for ourselves - more than enough if we didn't experience any problems - and so following a cross-examination of the cyclist regarding the road ahead, and a careful consultation of our maps, I gave him most of my water in anticipation of refilling at Bajo Caracoles some 75km (1 to 2 hours away).
We reached Bajo Caracoles without incident, ate lunch and refilled water.
Discussing the water shortage.
I also met Juergen in Baja Caracoles - driving his customized Mercedes Unimog truck - not your average SUV!
We carried on for a few more hours in the dirt and ripio, and eventually set-up camp on a hilltop beneath a unique rock formation somewhere on the Estancia Telken.
