Lightning and Forest Service Lookouts
Personally, I don't like being around lightning, especially in a boat with a tall aluminum mast. I just like it to keep it's distance! However, there are some pretty brave people who work for the Forest Service and do duty in the fire lookout towers.
The "cabs" are square (the "standard Forest Service design) and typically are raised up so the lookout observers can see down the slope of the mountain they're on top of. There are come cabs that are on the ground but they're in the minority.
The cabs have solid copper wire, looks to be about 3/16 to 1/4" in diameter that run down each ridge and down each corner of the square cab, and of course they're grounded. The azimuth table, or what ever they call it, is also grounded and I think the surface on the floor around the table. It's been a long time since I've been in one but this is from memory.
During a lightning storm the lookouts have to be very careful about what they touch, and in a way, don't touch. While a lightning storm is going on, if they see a "smoke" they have to get the Township and Range of the smoke then radio it into a dispatcher who then sends a fire crew out to put it out.
In the past couple decades many of the lookout towers have been decomissioned in favor of, I think, satellite positioning.
After a storm has passed, sometimes the Forest Service will send a small plane with a spotter out and they would fly up and down ridges and canyons looking for "smokes".
