There was another topic here that linked the video.
And as Louise mentioned, as photographers we know about white balance and the fact that the salt blows out meters to either insane white or a slight brown cast, early in the morning the salt is blue to the camera lens.
And also please read all of Russ Ayers salt report. The salt was covered with a layer of dirt from the mountains that surround the Salt Flats. And when pump back brine was sent back to the flats, it covered the dirt. Normally any dirt that covers the Flats, which it does from time to time, it doesn't get a layer of salt on the top and it dries and blows away.
I asked Russ if the dirt will migrate to the clay mud under the salt, he said it will take years to do so, the hope is the top salt surface dry and crack allowing the dirt to dry and blow away.
The Salt needs our attention, but the Sky is not Falling yet. And we have to be careful that all the attention and stress we give to the powers that be, don't cause them to say F*** It nobody can use the surface.
