Los Alamos is about 7300 feet, in the pine-piñon elevation, with some cottonwoods for variety. It is on mesas of a large plateau. I remember when it only was a private boys school, some of my friends went there for high school level, and I was unhappy that my family couldn't afford to send me there. The area is great for camping, there are pre-historic ruins nearby, and the great Valle Grande, a collapsed caldera, also is nearby, now a preserve with much wildlife.
The government moved in, built the labs, and it has grown to a town of about 23,000. Many people commute from nearby towns. The citizens living there are middle class, many with advanced degrees, and as a result theatre, music, dance and art are part of the recreational activities and festivals are well-attended by people from Santa Fe and the entire region.
I see no threat to nuclear materials, most of which are stored below ground level. Ten years ago, another forest fire went into the townsite. It is a research and engineering facility, no nuclear reactor is there.
