Thanks to all for your comments !
@eddyturn: There is no easy way to clean a van in Alaska and Yukon, so probably the first layer of mud protected the body from the new ones!
It's difficult to imagine how dirty VivaLaVida was. Needed more than half an hour to only clean the frame with high pressure washer and there is still mud in places...
@BrianW: I don't think that the yellow color was due to mining operation. There were mining activities there until early ninties but nothing since. But the soil there is of that color. I saw several rivers with the same tint.
The bird is a Great Horned Owl, viejo's wife is right. I didn't write it right, sorry...
@reelchef67: I choosed the high top mainly for insulation concerns and I'm happy with it. This one was espacially made for VivaLaVida. It's thicker than usual and contains insulation between fiberglass layers.
I'm working with a Sony A99 body and mostly Carl Zeiss lenses. The EVF is quite baffling when you look in the first times but when you get used to it, it offers many advantages, especially by showing in real time all the settings of the bodies. No need of test shoot anymore, the RAW file is what you see in the viewfinder!
@Viejo: thanks to your wife ! ;-)
@RandallDee: thanks !
