On Thursday's flight from San Francisco to Chicago. Above: Just east of Vernal, Utah. The view is to the northeast, across Dinosaur National Monument. Brush Creek flows down from the left (northwest to southeast). The Green River is the main stream snaking through the center of the picture. It flows from the upper right to the lower left in this picture. At left center, the river goes through Split Mountain Canyon. At the top of the image, you can see we're looking through a dirty window.
Below: View is to the north. The Green River flows from right to left (east to west) through Split Mountain Canyon. Split Mountain is the high, cleft behemoth on the far (north) side of the river. I can't find the name of the dramatic ridge in the foreground; the river is just visible flowing around its left (western) end. There's a campground right there where Kate and I had a sandwich dinner we picked up in Vernal while driving across the country in 2007.
For reference's sake: The river at this point is at about 4,800 feet above sea level. The peaks of Split Mountain are in the 7,300-7.400 foot range, and the unnamed foreground ridge tops 7,000 feet. The portion of the ridge in the closeup is about three miles long.
