The stocks of the West and East Spanish Peaks are seen here. The two peaks appear white because there is no vegetation present above treeline (about 11,000 feet). The other white objects are clouds. The change from light red to dark red around the peaks is due to the change from scrub oak and pinion trees to pine and fur trees. This area is know for its well-defined and well-exposed system of radial dikes. These dikes are focussed on West Spanish Peak. The "Great Wall" dike is seen in the upper left portion of the image and is almost 4 miles long and stands as high as 100 feet.
