In the summer of 1869, ScottishAmerican naturalist and author John Muir spent the months of June through September in the Sierra Nevada Mountains of California accompanying a group of shepherds while they led a flock of sheep to the high country to graze. During that time, Muir took every opportunity to explore the Yosemite area extensively—hiking, camping, writing, and sketching. Muir’s diary entries describing the land, flora, and fauna he encountered became the basis for the book My First Summer in the Sierra, first published in 1911.
Muir’s journal entries from that summer reveal his growing wonder and awe at the Yosemite landscape, as well as his endless curiosity for the natural world. On a grand scale, he trekked into remote areas for sometimes days at a time. He climbed Cathedral Peak and Mount Dana and trekked through Bloody Canyon to Mono Lake. On a more modest scale, Muir observed the flora and fauna that surrounded him with the keen enthusiasm of a naturalist. He described in detail the area’s trees, shrubs, flowers, mountain meadows, glacial features, and animals.
In the years that followed the publication of My First Summer in the Sierra, Muir went on to advocate for the protection and preservation of wild landscapes. In 1892, Muir cofounded the Sierra Club and became the organization’s first president. Muir also played an instrumental role in the establishment of several national parks including Yosemite, Sequoia, and Kings Canyon.
My First Summer in the Sierra remains among John Muir’s most popular works. The book’s inspired and lyrical accounts of an iconic wilderness, written at a time in Muir’s life when his character as a naturalist and wilderness advocate was taking form, earns it a prominent, influential place in the annals of nature writing and the history of wilderness preservation.
