Green River Emerging from Split Mountain Gorge, Dinosaur National Monument, Utah by Ron Schott

Originally intended to be about twice as wide, my Gigapan Beta unit contracted the deadly Whirling Dervish/Spiral of Death disease upon completing column number 38. (Fear not, it's fixed now - a relatively low tech solution, I simply "unwound" the robot. Aaahh, the joys of Beta testing!)

Nonetheless, the resulting image is a compelling look at the Weber Sandstone which is folded into an anticline (south limb visible in the gigapan) that is cleaved by the downcutting Green River. Hogbacks of the yellow and red Park City Formation lap onto the south side of the Weber like waves breaking on a beach. The red siltstones of the Triassic Moenkopi Formation form a strike valley at the right of the image - to the west this strike valley is known as the Racetrack as it wraps around the nose of the plunging Split Mountain Anticline.
