In the late 19th and early 20th Centuries, a number of talented photographers decided to their attention on the American Indian, wanting to record for posterity what was perceived to be a "vanishing race." The photos that ensued were often tremendously evocative ... none more so than the images captured by a man named Edward S. Curtis. I've admired his work for ages, and a print of one of his Montana photos has hung in my living room throughout my adult life.
Here's one of my favorite Curtis photos ... though not the one in my living room. This is a 1908 image called "The Scout in Winter," probably taken down in the Pryor Mountains of south-central Montana.
