The mysterious one

Big Bend National Park, Texas

You are looking at a twilight picture of one of the most remote and rugged mountain subranges in North America - the majestic Sierra Del Carmen of Mexico. To give you perspective, this shot was taken with a full frame camera at 70mm. This is about as close as you can get for this kind of view without crossing over the Rio Grande River into Mexico. This was captured on a rigorous three day backpacking trip on the Marufo Vega trail. This 33 second exposure was taken about 20 minutes after sunset in fading light.
