Marty,
I can see I'm going to have to add the Great Salt Lake as a place to visit for some shooting. I have to admit that most times when I'm going through SLC I'm usually on my way to someplace else (Grand Tetons, Yellowstone etc). These are some great shots and it certainly looks like you must have been freezing your fingers off to get these.
BTW: Have you seen evidence of the avian cholera epidemic there? Has it affected the raptors in addition to the water fowl?
