I had the pleasure to visit this fascinating place last summer. It is in the middle of nowhere in NW New Mexico. A huge place with miles of ruins to explore. We saw about half of it during our afternoon visit there. People lived there for several hundred years and then abandoned the complex quite abruptly. Why? The multi story building remains offer many photo ops. The masonry work is impressive. This is a 7 shot HDR done in Photomatix, raw files converted in DxO, Topaz Define used on the tonemapped image.
