We were hiking along Maroon creek in the White river national forest near Aspen, Colorado a few weeks ago and we came upon these trout hanging out in a shallow pool. The 12-14 inch Rainbows were very cooperative and let me get a picture with the 300 mm lens. The water in this stream is crystal clear with maroon colored rocks in the stream bed, hence the name. They were just hanging out waiting for a late season Blue Wing Olive Mayfly or midge to drift by for a meal. I can sit and stare into mountain pools like this for hours. It's fun to catch a grasshopper in the tall grass and throw it into a pool to see who's hiding under a shady undercut bank. It usually disappears in a splashing rise in short order.
