Isabella Bird began travelling while in her early twenties to help alleviate illness that had plagued her since childhood. She was a single woman in her early forties when she made her treck through the Rocky Mountains. A Lady's Life in the Rocky Mountains details this fascinating account of her travels through a series of letters written to her sister, Henrietta. These letters are filled with beautiful, vivid descriptions of the scenery, the people she encountered, the way of life, and a mountain man named Jim Nugent, that was as rough as they come, but a complete gentleman with Ms. Bird. She has the distinction of being the first woman to become a member of the Royal Geographical Society in 1892.
