If I had to bug-out with just two plants to restart somewhere as a primary food source, it would be cuttings of yam and moringa.
5) If you were to go out to the park today and dig a well, would there before enough groundwater to live off of? Is there enough water to support a small town on the park's 91,000 acres? (I think the character who owns the property wants to start building there, but he couldn't before because there wasn't enough water. This make sense?)
6) Would the swales lead to there being dramatically more ground water available for such use?
6) Could you explain how an aquifer differs from ground water? Also, what is the state of aquifers/ground water in that part of Arizona?
How does one test for the water level of an area and the likelihood of it supporting a well?
