The categories “sand, desert, river” are very important for understanding Spanish colonial designs. The Native people dependent greatly in these three elements, it was through them that they lived. Water was extremely significant to them, and it was through these elements that they preserved it. People of sand were from a place with low mountain ranges. Because of that, the people there came up with the “floodwater farmin” technique which is still used today. This technique means they collected all the water that fell on a rainy day. This water gave them the chance to grow goods which they used to survive. The Desert people lived in two different places depending on the season. During the Summer, they loved in field villages and during the Winter they lived in mountain homes. The River people, unlike the Sand and Desert people, lived in permanent homes. They had it easier because they always had water since they had streams. All of these people all had a huge respect towards the Earth.
