It was in the seventies when I started a project to find out something about the inheritance of colors in alpacas. I had to travel to Macusani ( 4 600 metres above sea level ),to look for color alpaca males, this town was at the foot of the Aricoma cordillera, province of Puno, Peru. It was so cold , I stayed one full day sitting in a room with cement walls, without heating, trying to warm up and to get over the head ache. We , Nicanor Condorena (from Juli, Puno) snd I were able to find a black (yana) and a grey (o'ke) hainachu alpacas. During the third day we had the idea of bathing and somebody guided us , in less than half an hour by car, to the town of Olaechea. This was the jungle, and had thermal waters, and it was so close to the altitude and to the cold weather.
At the end of the nineties I had enough time to visit the town of Paucartambo, province of Cusco. In the month of July there is an important celebration for virgin del Carmen. The town is all painted in white and the doors and windows are blue. One would say that the feast is a mixture of catholic and pagan dances from the time of the Incas or before. It is the dancing that makes more of the celebration. The town organized in barrios and each barrio has its own group of dancers. At two in the morning, there were cars to take people to watch the sunrise, higher in the mountains . The trip to the town of "Tres Cruces" takes about three hours, on a road that goes up, and up. We might have been some 4 000 meters above sea level when we got to the observation place. It was still very dark . I walked from the car to where people were standing. I wanted to be first in line, I slipped and people yelled, I came back to were people stood. When the sun started to light up, one could see the clouds below, massive clouds, kilometers to the right and to the left and in front. some colors changeg as the sun rose. Then, when there was enough light I could see where I had slipped during the dark early morning, it was the border of a precipice, more than a kilometer deep.
I do not know how many of this places are along the Andes, but they give me the idea that the easter side of the Andes is steeper than the western side of the Andes. They make me think that the Andes were the rim of an asteroid (or comet, or dwarf planet ) that hit the earth before the Pangea maps that we see.
