the news article left me wanting to know more about the hike, and i discovered this ropewiki article[0] which seems to be related, and link to a more detailed trip report[1]. i'm more of a peakbagger myself, but the photos of the canyons are fascinating (many examples in google images).

i'm guessing satellite locator beacons (such as resqlink, spot or in-reach) don't work very well in canyons. you'd need a much more monster antenna and transmitter.

We use an in-reach for text messaging at our cabin which is in the bottom of a gulch in the rocky mountains.

It does work, but only when a satellite happens to be in the right position. This basically means you have to queue up a message and it will get sent in 5-50 min.
