Hey Nolad,
Thanks for sharing. Do you know if that is the grand prismatic pool or the beauty pool (the second and third shots...,cannot remember the first though I have past it many times)? I think it is one of them. I have always wanted to spend a week shooting just the pools, but it always gets ignored when we are in those areas. It is too bad really as they are quite striking to see - no matter what type or time of day.
