[Utah-astronomy] Why?

Here are a couple of shots of the north arm of the Great Salt Lake I took while on our "crater" adventure yesterday. Can anyone explain whay the lake is this color, and what the white lines and streaks are? I think I know the answer, but want to hear what you all have to say. http://i1138.photobucket.com/albums/n534/brentjwatson/GSLFoamsmall.jpg View on i1138.photobucket.com Preview by Yahoo http://i1138.photobucket.com/albums/n534/brentjwatson/GSLFoam2small.jpg View on i1138.photobucket.com Preview by Yahoo
