Yosemite’s Ahwahnee Hotel was completed in 1927, designed by Gilbert Stanley Underwood. Its style, known as Natural Park Service rustic, developed shortly after the service’s founding in 1916, was among the first to aim to work in harmony with its environment, setting a trend that would grow in the state. The hotel’s materials–stone, wood, glass and concrete–blend perfectly into the scenery, especially Half Dome in the background.
