First published in 1911, My First Summer in the Sierra incorporates the lyrical accounts and sketches he produced during his four-month stay in the Yosemite River Valley and the High Sierra. His record tracks that memorable experience, describing in picturesque terms the majestic vistas, flora and fauna, and other breathtaking natural wonders of the area.

In the summer of 1869, John Muir, a young Scottish immigrant, joined a crew of shepherds in the foothills of California’s Sierra Nevada Mountains. The diary he kept while tending sheep formed the heart of this book and eventually lured thousands of Americans to visit Yosemite country.

John Muir (1838–1914) also known as "John of the Mountains", was a Scottish-American naturalist, author, environmental philosopher and early advocate of preservation of wilderness in the United States.
