I chose this photo because you can see where the clear water of Caswell Creek meets the silty Susitna River. The dividing line between the two waters is amazing. And for a bonus the clouds reflected off the water nicely. We calls those clouds "Simpsons Clouds" because they look like the clouds in the opening credits of the TV show.
P.S. I finally updated my Flickr site with the recent pictures. I added around 30 new photos.
