The Wawona Tunnel is a highway tunnel in Yosemite National Park. It, and Tunnel View just beyond its east portal, were completed in 1933. [1] [2]
Wawona Tunnel is named after the community of Wawona but its name origin is not known. A popular story claims Wawō'na was the Miwok word for "big tree", or for "hoot of the owl", a bird considered the sequoia trees' spiritual guardian. [3] [4]
Wawona Tunnel was bored through solid granite bedrock, and carries Wawona Road through a granite mountain on the south side of the Merced River. [5] It is located on one of the three main roads providing access to Yosemite Valley, the most visited section of the park. Wawona Road becomes California State Route 41 on exiting the park. After passing through the tunnel, when leaving Yosemite Valley, Wawona Road continues to Chinquapin Junction with Glacier Point Road to Badger Pass ski area & Glacier Point, and reaches an elevation of 6,039 feet (1,841 m) above sea level.
The completion of the tunnel shortened the trip to Yosemite by 40 miles (64 km) from Fresno and Southern California, compared to the All-Year Highway from Merced. [6] The tunnel's construction was paired with major road upgrades, which expanded a narrow, often steep 12-foot stagecoach road into a 26-foot wide road. These improvements lowered the road's incline to a gentle 5% and softened sharp curves, making it better suited for automobile speeds. [7] Additionally, the project rerouted the road away from old stagecoach relay stations like Fort Monroe.
When it opened in 1933, the Wawona Tunnel was the longest automobile tunnel in the world and remains the longest highway tunnel in California at 4,233 feet (1,290 m) long. [2] [8] The Tom Lantos Tunnels in Pacifica, California are 4,149 feet (1,265 m) .8 Miles long; the Caldecott Tunnel in Oakland, California is 3,771 feet (1,149 m) long. Both measured in their longest bores.
A $1.5 million federal highway contract to repair the tunnel's ventilation and electrical systems, and a separate contract to upgrade visitor services at Tunnel View, was completed in 2008. [1]
The Wawona Tunnel features in a monochrome photograph by Ansel Adams: From Wawona Tunnel, Winter, Yosemite, about 1935. [9]
Yosemite National Park is a national park of the United States in California. It is bordered on the southeast by Sierra National Forest and on the northwest by Stanislaus National Forest. The park is managed by the National Park Service and covers 759,620 acres in four counties – centered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, clear streams, groves of giant sequoia, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95 percent of the park is designated wilderness. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada.
Yosemite Valley is a glacial valley in Yosemite National Park in the western Sierra Nevada mountains of Central California, United States. The valley is about 7.5 mi (12.1 km) long and 3,000–3,500 ft (910–1,070 m) deep, surrounded by high granite summits such as Half Dome and El Capitan, and densely forested with pines. The valley is drained by the Merced River, and a multitude of streams and waterfalls flow into it, including Tenaya, Illilouette, Yosemite and Bridalveil Creeks. Yosemite Falls is the highest waterfall in North America and is a big attraction, especially in the spring, when the water flow is at its peak. The valley is renowned for its natural environment and is regarded as the centerpiece of Yosemite National Park.
The Merced River, in the central part of the U.S. state of California, is a 145-mile (233 km)-long tributary of the San Joaquin River flowing from the Sierra Nevada into the San Joaquin Valley. It is most well known for its swift and steep course through the southern part of Yosemite National Park, where it is the primary watercourse flowing through Yosemite Valley. The river's character changes dramatically once it reaches the plains of the agricultural San Joaquin Valley, where it becomes a slow-moving meandering stream.
Wawona is a census-designated place in Mariposa County, California, United States. The population was 111 at the 2020 census.
State Route 140 is a state highway in the U.S. state of California, 102 miles (164 km) in length. It begins in the San Joaquin Valley at Interstate 5 near Gustine, and runs east into Sierra Nevada, terminating in Yosemite National Park.
Mariposa Grove is a sequoia grove located near Wawona, California, United States, in the southernmost part of Yosemite National Park. It is the largest grove of giant sequoias in the park, with several hundred mature specimens. Two of its trees are among the 30 largest giant sequoias in the world. The grove attracts about one million visitors annually.
State Route 120 is a state highway in the central part of California, connecting the San Joaquin Valley with the Sierra Nevada, Yosemite National Park, and the Mono Lake area. Its western terminus is at Interstate 5 in Lathrop, and its eastern terminus is at U.S. Route 6 in Benton. While the route is signed as a contiguous route through Yosemite, the portion inside the park is federally maintained and is not included in the state route logs. The portion at Tioga Pass at Yosemite's eastern boundary is the highest paved through road in the California State Route system. This part is not maintained in the winter and is usually closed during the winter season.
Glacier Point is a viewpoint above Yosemite Valley in the U.S. state of California. It is located on the south wall of Yosemite Valley at an elevation of 7,214 feet (2,199 m), 3,200 feet (980 m) above Curry Village. The point offers a superb view of several of Yosemite National Park's well-known landmarks, including Yosemite Valley, Yosemite Falls, Half Dome, Vernal Fall, Nevada Fall, and Clouds Rest. Between 1872 and 1968, it was the site of the Yosemite Firefall.
Human habitation in the Sierra Nevada region of California reaches back 8,000 to 10,000 years ago. Historically attested Native American populations, such as the Sierra Miwok, Mono and Paiute, belong to the Uto-Aztecan and Utian phyla. In the mid-19th century, a band of Native Americans called the Ahwahnechee lived in Yosemite Valley. The California Gold Rush greatly increased the number of non-indigenous people in the region. Tensions between Native Americans and white settlers escalated into the Mariposa War. As part of this conflict, settler James Savage led the Mariposa Battalion into Yosemite Valley in 1851, in pursuit of Ahwaneechees led by Chief Tenaya. The California state military forces burned the tribe's villages, destroyed their food stores, killed the chief's sons, and forced the tribe out of Yosemite. Accounts from the Mariposa Battalion, especially from Dr. Lafayette Bunnell, popularized Yosemite Valley as a scenic wonder.
State Route 41 is a state highway in the U.S. State of California, connecting the Central Coast with the San Joaquin Valley and the Sierra Nevada. Its southern terminus is at the Cabrillo Highway in Morro Bay, and its northern terminus is at SR 140 in Yosemite National Park. It has been constructed as an expressway from near SR 198 in Lemoore north to the south part of Fresno, where the Yosemite Freeway begins, passing along the east side of downtown and extending north into Madera County.
The Wawona Hotel, located in southern Yosemite National Park, California, is a historic late Victorian mountain resort and one of the largest intact hotels of its kind within a national park. Originally established in the 1850s as Clark's Station, a pioneer stop, it soon evolved into a bustling stagecoach stop and later transformed into a grand New England–style resort, complete with manicured grounds and refined amenities. Its design catered to East Coast and European visitors, aligning with the era’s trend of exclusive grand hotels.
Badger Pass Ski Area is a small ski area located within Yosemite National Park. Badger Pass is one of only three lift serviced ski areas operating in a US National Park. It is situated five miles (8 km) south-southeast of the Chinquapin intersection of Wawona Road with Glacier Point Road in the southern area of Yosemite National Park. Glacier Point Road provides the access to this ski area. During high snow level and/or ski season, Glacier Point road terminates at Badger Pass Ski Resort. Under these conditions, the remainder of Glacier Point Road is used for cross-country skiing access to Glacier Point and other destinations in the high country.
Yosemite West is an unincorporated community and census-designated place (CDP) of resort homes located just outside the southern area of Yosemite National Park, just off Wawona Road, a continuation of State Route 41 from Fresno. It is a census-designated place (CDP), with a population of 47 as of the 2020 census. It is situated one mile (1.6 km) south of the Chinquapin intersection of Wawona Road with Glacier Point Road, at an altitude of 5,100 to 6,300 feet. The elevation reported by the USGS is 5,866 feet (1,788 m). The community is part of Henness Ridge, nearly 3,000 feet (910 m) above the southern banks of the Merced River and State Route 140 from Mariposa. Addresses in this area are shown as "Yosemite National Park, CA 95389".
The Wawona Tree, also known as the Wawona Tunnel Tree, was a famous giant sequoia that stood in Mariposa Grove, Yosemite National Park, California, United States, until February 1969. It had a height of 227 feet (69 m) and was 26 feet (7.9 m) in diameter at the base.
Yosemite National Park is located in the central Sierra Nevada of California. Three wilderness areas are adjacent to Yosemite: the Ansel Adams Wilderness to the southeast, the Hoover Wilderness to the northeast, and the Emigrant Wilderness to the north.
Chinquapin is a former settlement in Mariposa County, California. It was located 8.5 miles (14 km) north-northwest of Wawona. It is located within Yosemite National Park, adjacent to the community of Yosemite West. Chinquapin is the midway point between Yosemite Valley and Wawona, a community inside the park.
The January 1997 flood of the Merced River occurred from December 31, 1996, to January 5, 1997, throughout the Yosemite Valley in Yosemite National Park, Mariposa County, California, US. The flood stands as arguably the park's worst natural disaster to date, and inarguably the worst flood in park history. The Merced River at Happy Isles peaked at 10,100 cubic feet per second during the flood. A book was written on the flood later in 1997 by Mark Goodin titled Yosemite: The 100-Year Flood. It is part of the 1997 California New Years Floods.
The Yosemite Valley Bridges are eight bridges in the Yosemite Valley of Yosemite National Park, most of them spanning the Merced River. Five of them were built in 1928, with the remainder built between 1921 and 1933. The bridges feature a concrete structure faced with local stone, in an elliptical or three-centred arch configuration. They are notable for their uniform character and for their conformance to tenets of the National Park Service rustic style. Design work for the seven newer bridges was by George D. Whittle of the San Francisco District Office of the U.S. Bureau of Public Roads for the National Park Service. Concrete bridges were chosen at the urging of Thomas Chalmers Vint of the Park Service, in lieu of alternative designs for steel truss bridges, or suspension bridges suggested by the park superintendent.
The Wawona Covered Bridge is a covered bridge spanning the South Fork Merced River near Wawona, California, in Yosemite National Park. The open bridge was built by Galen Clark, the steward of what was then called the Yosemite Grant, in 1868, without its cladding. The open bridge was a component of Clark's proposed new road from Wawona to the Yosemite Valley. Clark was unable to complete the road, which he sold to the Washburn Group of investors along with his stopover lodging in 1874. In mid-1875 the Washburn Group completed the road to Yosemite Valley. It is one of twelve remaining covered bridges in California.
The Yosemite Stage and Turnpike Company, established in 1882 by Edward, John, and Henry Washburn, was a 19th-century transportation enterprise that provided stagecoach services connecting the San Joaquin Valley to Yosemite National Park. The company played a significant role in developing Yosemite's early tourism infrastructure, including the Wawona Hotel, helping to make the park more accessible to visitors.
