LANL was founded during WWII as the secret atomic weapons lab for the Manhattan Project. The atomic bombs dropped on Japan in 1945 were developed here.

We need water!! (SOL II. 32, II. 33, II. 34) Colorado River was dammed. Good thing: Gives much needed water!! Bad thing: Harmful to environment. Caused native fish species to become extinct.
