JPEG...Pristine Skies in the US
      05/21/08 10:53 PM

About 10 years ago I ran into a gentleman on the internet that hosted a dark sky site. He basically gave a dark sky index if you can give lat and long.

I realized that given his data set that he could easily generate a map of the United States where NO SKY GLOW IS VISIBLE.

I asked him to do that and he did.

Here is his map. I'm sorry I have lost track of his name. From what I can tell from my experiences in the western US the map is fairly accurate. It does not include the influence of lights from Canada or Mexico. It also does not take into account elevation.

So here it is....the sad part is how few places there are in the United States where no glow is visible on the horizon. If your east of the great River...sorry.

Eastern Oregon and northern Nevada are your best bets. Portions of southern Utah might also work.

This data is over ten years old, but it would be interesting if somebody could redo the image.
