The tamarisk and cane wound through the steep sided valley bottom like a golden thread. The trail was littered with the droppings of an animal we guessed to be mountain goats, and sure enough as we reached the tarmac road at the top of the mule track we saw a herd of them bolting away across the mountainside. Turning off the road again we passed an old water cistern built 100 years ago before descending on a zigzag track back to the riverside and another series of mostly abandoned fincas.
