The BLM permit for 2000 defined a closure area that has been used through 2003 -- see
http://www.nv.blm.gov/Winnemucca/recreation/burningman/index_old.htm
"Burning Man 2000 Permitted Event Site"
(PDF file)

center:
40° 45"17.162029' N, 119° 14"11.105358' W
corners:
40° 44"16.037027' N, 119° 14"25.654737' W
40° 45"7.844786' N, 119° 15"31.495004' W
40° 46"14.137633' N, 119° 14"45.292642' W
40° 46"0.145847' N, 119° 13"12.925586' W
40° 44"47.25034' N, 119° 12"59.484942' W

This defines the center & corners of Black Rock City's pentagonal trash fence, +/- fifty feet or so. The Man is located at the center. Not certain what datum was used -- possibly NAD27 or whatever was used on the base map.

Topozone lets you zoom in and out at various map scales:
http://www.topozone.com/map.asp?lat=40.75481&lon=-119.23643&s=200&size=m

AFAIK no recent satellite images at similar resolutions are available without paying NASA for a flyover. Terraserver had 5-10 yr old images last time I checked.

Thanks for posting those Badger, Do you have any Sat images taken during the event? (or were those taken during the event and we're so small that we can't see ourselves?) Thanks again.

In other news, an extremely large woman dropped a blue bikini top in the Nevada desert.

I REALLY like the first shot because in the lower right of the pic you can make out the ancient shorelines as Lake Lahanton gradually receded.

Oh, and in the far right (middle) you can make out the two 'hanging' playas that are about 30-60 above the main lake bed.

There's a few websites where you can purchase or schedule a photo of the playa. But I don't think you can schedule a date for a photo (thus it would take EXTREME luck to have the satellite passing overhead during the week of BM). The satellites take groups of photos in big longitudinal batches.

Nice images Badger. Do you know why one lake is black and the other blue in the second image? (I'm presuming they are both lakes)

Nice question. I'm assuming that because the second image is a false color composite that it probably has to do with a temperature differential possibly due to shallowness of the two bodies of water. It might also be due to chemical composition of the water although that's a real leap as far as guesses go.

Could it be due to the light refraction angle due to the depth of the water?

I don't think a false color image is affected by things like that, but it's been a long time since I had to remember that info...

like my new icon? It's sphene!
