I lived, worked, and rescued in Arizona for about three decades. Where in Arizona will she be located? Flagstaff, elev. 7000 feet, and Phoenix, elev. 2000 feet, are essentially on different planets with respect to climate.

The great thing about AZ outdoors is the great variability in climate, corresponding with elevation changes. You can go from desert to snowshoe country in less than one hour.

I am a definite fan of paper maps, much more versatile than the GPS units perhaps a premium Gaia subscription.

If she is in th Phoenix area, she will be in definite desert country and will need hiking gear for those condition, but mountains are never far away. She will probably need equipment for that environment as well.

Good problem to have!!
