I think not; it's not somewhere you can conduct a nuclear test without starting a war with Mexico. However it is interesting to look at the TFR area in Google maps; it looks just like a nuclear test site, but the craters are natural volcanoes.
Mexico isn’t going to start a war with the US. it would last a week at most, and they’d end up glowing even more than if the us ‘downwinded’ them all year.
Well, somebody has suggested nuking a tornado before. Why not a vulcano?
