In this classic work, naturalist John Muir offers a passionate and detailed account of the majestic landscapes of California, particularly the Sierra Nevada mountains. Through vivid descriptions, Muir captures the beauty of the region’s towering peaks, lush forests, and glacial valleys, while also sharing his deep knowledge of the area’s flora, fauna, and geological history. This book not only reflects Muir’s love for the wilderness but also helped inspire the early conservation movement in America.
