The camping trip taken by the "conservationist president" that put America's national parks on the map—from the award-winning author of Roadside Baseball.

During his whirlwind 1903 tour of the western states, President Theodore Roosevelt paid his first visit to California. In between the appearances and pageantry, he embarked on three days of epic adventure in the wilderness of Yosemite with the famous and influential naturalist John Muir. A lover of the rugged outdoors, Roosevelt was humbled and impressed by the camping trip, which proved to be one of the most important sojourns in presidential history. Through firsthand accounts, speeches and rare photographs, author Chris Epting tells the story of a great and profound journey that had a lasting effect on conservation history and the National Park System.
