I read an article from a fish & game official on avoiding being eaten by grizzlies. Since there are no grizzlies in the dessert I am fairly safe but in the quest for knowledge I'll share what I learned with the GBO family.
In grizzly country it is reccomended to wear small bells and carry pepper spray. When you see bear tracks you follow them until you see a poop pile. Black bear poop contains berrys, nuts etc, Grizzly bear poop contains small bells and smells like pepper. In that case you should go the other way.
