One of those cheesy little waist pouches on a belt, with the pouch at her back could have held a space blanket, some matches, tinder, a mirror, cellphone, whistle, etc.

A cellphone MIGHT not have worked, but I've been around Moab, and what they called a 'canyon' could have been more like a shallow ravine. And I'll bet she didn't know that a cellphone signal wouldn't get out.

I suspect that it was the old "It's never happened to me before, so I'm sure it won't today".

And I'll bet her family went into her home to look for clues. A cheap, easy quick one would have been a note on the kitchen table: "I'm going running at..............., from about (point A) to (point B), Wednesday, 12-20, 9:30 am. Back by 2:30 latest. Taking Taz."
