Having filled my belly up on Wintergreen berries and wondering "How in the hell did I get to Wisconsin and why is there a damn canyon here!!", I have calmed down to think things out. Of course, staying calm also prevents those berries from turning into diarrhea. Anyway, moving on.

DeanLogic is alone (but with a crowd) and unarmed carrying a Magnesium Firestarter and some red berries.

I guess I can't keep throwing other people in the canyon in order to stack up bodies to cross, so...

OPTION 4 - Move down the canyon to a fallen log and attempt to cross the canyon on that.
