Hi Frank

It may not be perfect but it sounds like we both think the Salt Flats to have appropriate topography for celestial.

I'm still trying to answer Lu's student's question.  Where on earth, aside from bodies of water, is the surface appropriate for celestial.

The mountains could even help by providing contrast since the salt itself seen against the haze of the low altitude sky might have very little contrast. You can poke around out there a little bit in Google Maps (Street View and other photos). Park yourself on I-80 and look at the horizon. I noticed one problem right off: floating islands (see attached). Certainly for some times of day, the refraction could be prohibitive.
