I gather some parks service's still employ fire spotters.
Basically sit on your duff all day, dust off the old bino's every few hours......might have to use a radio occasionally and have a basic knowledge of mapping though.
Heard some stories from the old days, where they actually camped/lived there out in the wilderness, and filled in time hunting or fishing.
Excruciatingly boring i gather, but its probably more involved than that now.
Very high duff factor.
