Bar T Ranch, Colorado

I enlarged the original photo to get a better look at the two people .. I thought to be two women, but maybe a man and a woman, I know it is hard to tell, but the dress on the woman, who is on the left appears to be Late 1800's to very early 1900's style. And may or may not be Anna M. Ballard.

Anyone know anything about the Bar T Ranch in Watkins, Colorado?
