Women were scarce enough in the West of the late nineteenth century, and a middle-aged English lady traveling alone, by horseback, was a real phenomenon. It was during the autumn and early winter of 1873 that Isabella Bird made this extended tour of the Rocky Mountain area of Colorado. The letters that make up this volume were first published in 1879. They tell of magnificent, unspoiled landscapes and abundant wildlife, of encounters with rattlesnakes, wolves, pumas and grizzly bears, and her reactions to the volatile passions of the miners and pioneer settlers. A classic account of a truly astounding journey.
