Over the first half of the day we picked our way cautiously along the path, peering carefully around blind corners with concern for oncoming buses, trucks, or collectivos (mini-bus cabs) that might appear - bearing down at almost uncontrollable speed.
The GPS did give us an indication of progress - by noon, we had covered only 80km's at an average speed of less than 20km's per hour, and a top speed of only 44kmh. We had no time for any kind of substantial lunch, and settled for bread and water beside the Rio Bamba bridge.
The Rio Bamba flowing fast and brown.
After the Rio Bamba, the terrain and climate change dramatically from lush tropical to semi-arid, but following the climb out of Ocros, we saw a new kind of landscape - high alpine plain with short plants and grasses and moss in unusual shades of gray-green, and lichen covered rocks.

Eventually, we found ourselves descending into the Ayacucho valley, through the plains where Simon Bolivar and company inflicted the deciding victory over the Spanish in the war of independance.
We found a nice hostal tucked away in a courtyard just off of the Plaza des Armes, in an area of 16th century colonial buildings - had an early dinner and were done for the day!
