Grand Canyon, AZ - The twenty-first annual Grand Canyon Star Party will be held from Saturday, June 18 through Saturday, June 25, 2011 on the South and North Rims of Grand Canyon National Park. This event is sponsored by the National Park Service, the Tucson Amateur Astronomy Association (South Rim), and the Saguaro Astronomy Club of Phoenix (North Rim), with funding from Grand Canyon Association.

Amateur astronomers from across the country will volunteer their expertise. Free slide programs will be offered; and numerous telescopes will be set up to view planets, star clusters, nebulae, and galaxies at night and to view the sun by day. National parks such as Grand Canyon are protective harbors for some of the last remaining dark skies in this country. Weather permitting, expect spectacular views of the universe!

On the South Rim, events include a slide show nightly at 8:10 p.m. in the theater of the Grand Canyon Visitor Center.The slide show will be followed by free telescope viewing behind the building. To guarantee a seat at the slide show, arrive a few minutes early. Telescope viewing continues well into the night; visitors may arrive anytime after dark.

Parking for the South Rim Star Party is available in lots 1 through 4, or visitors may arrive by the free Village Route shuttle bus, which runs until 11 p.m. Visitors will need a flashlight for the walk to the viewing area, but are asked to keep flashlights pointed down to protect everyone's night vision.A red flashlight is best, and can be made by covering any flashlight with red cellophane, nail polish, or magic marker.

On the North Rim, telescopes will be set up on the porch of the Grand Canyon Lodge every evening. Check the Visitor Center and park bulletin boards for additional daytime and evening events.

Nighttime temperatures on both rims can be quite cool, even in summer. Those attending the star party are encouraged to bring warm layers of clothing.

When traveling in the park on the South Rim, it is best to find a parking space and use the free shuttle bus system to access points of interest in the Grand Canyon Village area. See the Park Guide for tour bus routes and schedules. If you plan to stay overnight at Grand Canyon National Park, plan your visit well in advance.

The Grand Canyon has to be a pretty good low level light pollution area. The nearest high light pollution areas would be Flagstaff, Las Vegas and St. George. I used to have a website on my favorites that was a map of the U.S. that showed the U.S. based on light pollution, but I can't find it on the internet anymore. Anyone know what website it is?
This is a great site.

Very very interesting.
I would have guessed that Northern Wisconsin had less light pollution than Yosemite.
I still think Yosemite may have more due to The Turlock Effect (light being blown in from Turlock).

I went into my backyard often when I was back in Wisconsin and admired all the
intelligent life out there. My mind remembers a night sky much more brilliant than
what is currently available in Yosemite backcountry.
I wonder if I'm being tricked again...

Google "U.S. light pollution map " for a variety of choices.
eeek's post is better.
There is a scale regarding darkness. I found a very detailed map with scale explanations when I was reading an astrophotography site, but I've lost the link sad smiley I do remember seeing that in the U.S., the area with the combination of cleanest air and lowest light pollution was somewhere in southeastern Utah.

Natural Bridges, UT was what I was thinking of. One of least light-polluted skies in the continental U.S.

I remember reading somewhere Great Basin NP was stellar (haha) for dark skies.

Turns out Marmuts have invaded that place too though.
