Did you mention prickly pear earlier? If so, and they're like black bear in AZ, they'll get into those for the fruit.
Got ground squirrels/marmots? Yep.
Fish in the creeks? Yep.
Deer and the antelope play there? Yep.
If there's a bear around you can pretty much guarantee there's food in the area of some sort, or it would leave to go find some.
Again, good luck on your hunt.
