For those looking for documentation of the salt conditions. A mention was made earlier in the thread about historical information like aerial photos of the salt flats.
They are all out there but it will take someone with a lot of time on their hands to dig through the images to see what they can find.
I used to be in charge of maps for our emergency management agency, and would go over to the Denver Federal Center to pickup maps.
They had a product called "orthophoto quads" which were aerial photos that matched up with each of the 1/24:000 topographic maps.
You could order prints of them. They often had several versions of the images sometimes dating back to WWII period and earlier.
It appears that all or most of that data is now available on line but it takes some messing around with the applications to figure out how to get to what you want.
Start here :
http://nationalmap.gov/ortho.htmlhttps://lta.cr.usgs.gov/Single_Frame_RecordsLat long you want to search for is those values near 40.763551, -113.896156
You can eventually dig down and find individual images with all their associated data like this which was captured in June 29 1981
It was shot at an altitude of 65,000 ft and the original is a 9"x9" aerial photo negative (which means the real image has tons of detail available):
