A week ago Marathon and I did a three-day trip to an area in the northern part of the southern part of Chile (not patagonia).
Finding a place to camp generally wasn't hard, with lots of unowned, unguarded areas. The fast-flowing river that shifts land over time helps this effect.
I could yarn along describing the place, but I'll just do an picture dump instead.
Disclaimer -- I am not a fan of the Crimson Tide.
Can you pick out the zigzag pattern on the hill below? It's from cattle grazing.
Yes, I am technically lying on a road.
Those are steers. We didn't know, got a nasty scare at around six in the morning (complete darkness) when one of them walked up to our sleeping bags.
