In my experience, if they get spooked they'd run down the trail or turn around... They'll probably stay on their feet. The key is to stay with them ;~D
I've never seen one that acts so stupid as to seem unaware of how steep the bank is. And we have a lot of steep ground around here.
How in the world do they turn around on a trail that narrow. There were places were there was rock wall right up against the high side of us. I didn't take any pictures because I wasn't letting go of the horse:)

You ever find out what happened to that one in Oregon?
