Apologies for the word problem. I'm sure there's a simple solution or two, but I'm trying to work out a real world scenario. We used to indoor top rope belay but that was years ago in boy Scouts so our rock climbing knowledge is incomplete and rusty. We've fished this area for years without needing rescue equipment but as everyone gets older and with the level of parkour required to fish this creek, I feel it's time to be more prepared.
Likely scenario: pair of fisherman radio for help with sprained/broken ankle. Unable to follow creek rest of the way to the exit point.
Worst case scenario: single fisherman misses 15 minute radio check-in. Assume unconscious.
Environment: single lane (shared w/ oncoming traffic) mountain road follows creek being fished. Approximately 5 miles between entry/exit points. Road can be as much as 50 feet above creek and incline can be as steep as sheer cliff face though it's usually a sharp incline with near unclimbable shifting gravel. 1 hour drive from cell service, another 1 hour drive to Gunnison hospital.
Rescue team: pickup truck with two adults. We'll drive up till we spot fisherman. Probably anchor to the truck or nearby pine trees, blocking the road for other campers/fisherman. Alternate route for them would be a 5 hour drive around so I believe blocked traffic will wait.
Question: What gear should we prep for potential emergency rescue? I'm assuming this is similar to crevasse rescue without ice picks?
