A collection of letters details Bird's long journeying through the Rocky Mountains, into the heart of the land, often unaccompanied, only choosing her routes based on her preference of the moment and always willing to deviate from the plan. She wrote beautiful descriptions of a time and place much changed today, appreciating the remote wildness she found on many of her tramps. In addition to her natural writings, she also turned her eye on the people who inhabited these lonely, majestic places as well and her character depictions are delightful. She has captured the character of the folks who chose to eke out a living homesteading in the shadows and valleys of these majestic mountains, capturing the fortitude, the sometime lawlessness, the hospitality, and the suspicions of her hosts and acquaintances.
