Does anyone know the history of Glamis or where I can look up the history of when it was used by the military or whatever else it was used for...

Glamis is actually called the Algodones dunes. I might have spelled it wrong however. Look up a search engine using this name. You will find many articles/history.

Well it's not a perfect answer but here's a page with information about some of the military bombing practice taking place around the dunes and at one time in the dunes:

Download a copy of the Draft RAMP from the BLM website. It has some interesting information. Plus you'll be more informed for the upcoming RAMP meetings.

Thanks to everyone who replied. I didn't think anyone was going to... I got some helpful/useful information. Thanks again.
