My First Summer in the Sierra is perhaps the most lyrical, joyous, and engaging of all John Muir's many works. In the summer of 1869 Muir took work as a sheepherder in order to explore the headwaters of the Merced and Tuolomne Rivers. Keeping notes in the form of a diary, Muir describes his fellow companions-human and otherwise-with exquisite compassion, interest, awe, and even humor. This Warbler Classics includes all of the sketches by Muir that appeared in the first edition of the book and a detailed biographical note.
