Hi! Please!

Does anybody tell me what this is? Is it human made? If not, what is it, geologically speaking? Looks like sand, but I don´t understand the change of its colour

Thanks!

Well it is a river bed. My guess on why it changes colour is the underlying rock but can't say more than that.

This white snake (as named by many here) is a dry river. It might be flooded every once in a while, but judging for the precipitation rates in the area, that may be very rare.The white color is due to the salt accumulation at the surface. These salts were accumulated over time during the desiccation of the river. You can see many other water bodies in the surroundings that underwent the same processes. The southern end of the snake has been covered with sand, and it is very likely that the same will happen all along the river. It looks like both ends actively drain down to the sea when it rains (you can tell by the sediment in the deltaic lobes that come into the sea). There is an even larger saline water body to the south (zoom out and check it out!), which water is draining down to the sea.

Very interesting, thank you

Apparently, calling it snake wasn't a bad guess eventually

Actually it is a tidal slough. If you go to 38°12'7.70"N, 122° 2'48.45"W you can see one that has water in it (in California). The snake used to be part of the Colorado River Delta, but since no fresh water makes it to the delta anymore, the delta has died out. The white is salt that has accumulated.

We killed the snake man! Save the wetlands and support wetlands restoration!
