The Black Mesa Research Facility,[9] or B.M.R.F. for short,[10] and colloquially known as Black Mesa[9], was a scientific research complex built around an abandoned Cold War ICBM launch silo in the New Mexico desert in the United States. The site was the location of the Black Mesa Incident, the result of a Resonance cascade which would have catastrophic ramifications upon the planet for years to come. The facility was destroyed by a thermonuclear explosion one day after the cascade.

Taken from this page (https://half-life.fandom.com/wiki/Black ... h_Facility) which would give you more detail.

I really want a resonance cascade to happen!

Are you with me?
