mindgarden saidLOL. It's not that much methane. What you see is a cumulative signal from adding together many satellite images over many months. Plus playing a bunch of mathematical games with the data to account for cloud cover and land color. (Which is why they were not sure that it was real in the first place.)
Anyway, methane is not a health hazard. I do know of a number of water wells where they can actually flare off the methane before it goes to the pressure tank, but not in that area. The only health hazards that you need to worry about are heat stroke, dehydration, rattlesnakes, scorpions. Maybe altitude exhaustion if you don't realize how high up you are.
Of course, another interesting geology story in that area is the uranium and thorium concentration in those same rocks. But that is really only a potential hazard to people who live and work in the stuff for long periods of time - not to people driving through.
