The study of American national parks provides invaluable insights into American intellectual, cultural, and sociopolitical trends. As very popular tourist attractions, parks are also depicted in art, film, television, books, calendars, posters, and a multitude of other print and visual media. National parks therefore exist both physically and in the American imagination. Comparing Yosemite National Park, one of the oldest and most popular national parks, to Mineral King, California, a relatively unknown and far less-visited region in Sequoia National Park, unveils the deep complexity of the national park idea. From the mid-nineteenth to the late twentieth centuries, the visual and written representations of each area, including art, photographs, advertisements, and government publications, evolved and shifted, sometimes rapidly and paradoxically, depending upon the aims and needs of historic societies. The power of imagery and production of knowledge to influence visitation, management, and land designation is revealed through this comparative study. Park representation and interpretation in the cultural consciousness, moreover, uncovers how societies perceive and, thus, will ultimately use certain environments. A place cannot truly become a national space until it is viewed and valued as such in the American imagination. The creation of cultural material, especially visual works, is vital for forming and sustaining national park narratives. Popular parks like Yosemite need to have their legacies reinforced, and lesser-known units, such as Mineral King, deserve the chance to have a cultural legacy created—thereby helping to ensure that both remain for future generations.
