This image is a 9x12" watercolor on Arches 140# cold press paper, using Daniel Smith Prima-Tek watercolor paints with some touches of gouache. The Prima-Tek paints are great for landscapes, especially those with rocks or cliffs in them because the paints are mineral based and have a natural texture and granulating characteristics to them that lends itself well to rocks. This was painted from a reference photo my neighbor took this August on his 15-day float trip through the canyon. Although the canyon is fairly large, it has the feel of a slot canyon, becauuse most of it is in shaded light due to the towering canyon walls. The one spot of direct sunlight where the stream disappears around the bend attracted me to the image - that spot gives a natural focal point and is a nice contrast with the colors and shaded lighting on the rest of the canyon. The water really is a chalky blue there, due to dissolved minerals in the water.
