How South Mountain Was Formed
The South Mountains were created by huge forces deep inside the Earth. Scientists believe they are a special type of mountain called a metamorphic core complex. This means they formed when giant pieces of the Earth's crust, called tectonic plates, slowly moved. These plates pushed and pulled, causing the land to rise up and create mountain ranges like South Mountain.
The area around Phoenix looks flat, almost like a big lake with mountains rising out of it like islands. This flat area is actually a large basin filled with dirt and rocks. Underneath this flat land are more hidden ridges, similar to the South Mountains. These buried ridges are about one kilometer tall and spaced about one kilometer apart.
A Sacred Place
The South Mountains are very important to the Akimel O'odham and the Kwevkepaya people. Both groups consider these mountains to be sacred. This means the mountains hold deep spiritual and cultural meaning for them.
