Before the european invasion, the land from the utes was full of dessert, forest,waterlands, mountains, and their was defenetly no roads like there is now. As you can see, some of the landforms have dessapeared because of building roads houses and buildings. Alhtough they have also preserved some of their waterlands and mountains as you can see in both of these pictures, that were taken from lake Riverside CA, and from the Colorado plateau.
Pictures taken at google earth by me.
