Native American Woman on Horse with Travois and Child

This is an incredible image, that shows a Native American woman on a horse, pulling a travois and child.  There are not many other details in the image to suggest a time and place, other than the (relatively) modern building and corral in the background.  I image 1900's-1910's given the timeframe of other photos in this batch, but other than that it is anyone's guess.
