Just east of where the Continental Divide slips through Stony Pass in the Colorado Rockies, from the small seepages pulled by gravity from the slopes of Canby Mountain, a stream is born that, in time and distance, will gather many other streams on its way east and south before flowing into the Gulf of Mexico on the oriental side of Brownsville, Texas, 1,885 river miles away. For many of those miles it will form the international border between the United States and Mexico, but as its route flows duely north-south through the high desert of New Mexico, passing west of Taos, it drops through a great gorge formed in the rift valley of the San Luis Basin. As the river emerges from the gorge, it moves along rather quietly among low sandstone walls lined with cottonwoods and rabbit brush. When the Ancestral Puebloan people abandoned Chaco, Mesa Verde, and the canyon dwellings of Cedar Mesa, many of them found their way to pueblos already established near the long crawl of the Rio Grande. It is a great desert highway filled with culture and history much older that the settlements of Jamestown or Plymouth.

A focal length of 48mm, quite normal, gave me the intimate angle-of-view I wanted. An aperture of f/20 provided depth-of-field, and a shutter speed of 1/6th second at ISO 100 gave me a medium overall exposure. The highlights and shadows were neither so bright nor so deep that the exposure was blown out, or blocked up, on either end of the range.

The mighty Rio Grande leads us on a journey through time and teaches us that even in the desert life can find water to sustain itself.
