It's easy to be fascinated by these rough-and-tumble frontier women. Cowgirls defied the gender norms and expectations of their time, trading skirts for chaps and housework for horses. In the 1922 book "The Cowboy: His Characteristics, His Equipment," author Philip Ashton Rollins claims women weren't an important factor in the West because there were so few of them. Despite the existence of Calamity Jane or Cattle Kate, Rollins wrote that "ranchwomen's" influence was pretty much limited to their households. He never met these seven extraordinary women.
