A bit off topic, but I spent 5 years in Arizona and hunted the northern part with my wife and her family for elk a few times. They are from there. It was amazing that large parts of northern Arizona have no surface water at all. There are huge pipelines that ranchers have put in for hundreds of miles that put water in essentially waterless areas both on private and public land. That in addition to dirt tanks that gather rain water, is why there are elk and deer in many of those areas. Historically elk didn't live there because there was no water. The ranchers did that. My father in law's wind mills water a lot of wildlife in addition to his cows.
