From Yellowstone's Canyon Village to Yosemite's Tioga Road, Mission 66 physically reshaped the most iconic parks in the American West.
Mission 66 applied suburban zoning to the wilderness, relocating human activity away from fragile natural wonders into concentrated 'villages.'
Mission 66's most dramatic impact was in the iconic parks of the American West. Here, accommodating millions of automobiles forced the NPS to completely redesign the relationship between human infrastructure and wilderness.
In Wyoming, the NPS implemented "segregation of uses," essentially applying suburban zoning to the wilderness. The goal: remove lodging and commercial activity from fragile natural areas and consolidate them into durable "villages."
In Yellowstone, this meant demolishing the historic 1910 Canyon Hotel, deemed dangerously close to the Grand Canyon of the Yellowstone. Canyon Village rose a mile away, preserving the canyon edge while consolidating gas stations, cafeterias, and motels into a serviced commercial zone.
At Grand Teton, the Jackson Lake Lodge (1955) was the aggressive new aesthetic made concrete. Designed by Gilbert Stanley Underwood, who had previously designed rustic masterpieces like the Ahwahnee, the lodge was a stark 300-room concrete structure with a flat roof.
Critics called it a "concrete monstrosity." But Underwood's floor-to-ceiling picture windows turned the building into a viewing platform that framed the panoramic Teton Range. The modernist Colter Bay (1956) and Moose (1958) visitor centers followed.
At the Grand Canyon, Mission 66 redesigned the entire South Rim. Cecil Doty designed the Horace M. Albright Training Center (1961–1966), a modernist campus for training the expanding ranger corps.
The era also produced the Shrine of the Ages, an interfaith chapel designed modernist interpretation of a Native American kiva. Originally planned on the rim with hydraulic altars, it was relocated inland, an early tension between development and preservation.
In Yosemite, the reconstruction of the Tioga Road became one of the era's most controversial projects. The old route through the high country, forged in 1883 by Chinese laborers in 130 days, was utterly inadequate for modern traffic.
The NPS blasted through pristine granite near Tenaya Lake to meet highway standards. The sheer scale of environmental destruction alienated conservationists and marked an irreversible turning point.
At Glacier, the Logan Pass and St. Mary Visitor Centers serviced the Going-to-the-Sun Road with low-angled rooflines built to withstand crushing snow loads.
At Olympic, the Hurricane Ridge Visitor Center, tragically lost to fire in May 2023, and the Heart O' the Hills entrance station streamlined the growing flow of vehicles.
In Death Valley, Cecil Doty's Furnace Creek Visitor Center (1959) used deep overhangs and massed walls to provide an oasis in the desert. At Rocky Mountain, Taliesin architects designed the Beaver Meadows Visitor Center, now a National Historic Landmark. And at Zion, the Oak Creek visitor center joined Doty's expanding portfolio.
Traditionalists attacked Jackson Lake Lodge 'slab-sided concrete abomination.' But its floor-to-ceiling picture windows fundamentally changed how visitors experienced the Teton Range.
