I initially discovered the desert southwest of the United States because of the vast landscape and unique slot canyons but fell in love with the small structures left by the ancestors of the modern Pueblo Indians. These small granaries were built under overhangs hight above the river valley. The all face south to catch the winter sun. They also command very defensive positions. They were built before 1300 a.d. when the great Anasazi trading culture disintegrated for reasons a mystery to this day.
