In the middle of the desert, the humans overcome nature once again by doing what is often despised of beaver colonies: we have constructed a way to capture precious water for our own purposes. Even though it seems out of place, Lake Powell is a retreat in the middle of some of the hardest desert in the states. The air is humid in a way that doesn't seem natural, so if you don't have watercraft (for fun or by necessity), you probably don't want to be here. The elevation is low so it can get pretty hot even in September. Make sure your car has an air conditioner that works well and don't trust the condition of an unpaved road by whatever map you have.
