Oneonta Gorge is a spectacular moss, lichen and fern clad slot canyon located on the Oregon side of the Columbia Gorge. With cliff walls towering some 150 feet to the forest above, the lower gorge has been cut by Oneonta Creek through layers of basalt flows dating back 25 million years ago to the Miocene epoch. Oneonta Gorge The Oneonta Gorge is a picturesque canyon residing in the Columbia River chasm area of the American state of Oregon. This area, being a habitat of unique aquatic and woodland plants, has been designated as a botanical area. Oneonta Gorge is known as “one of the true dramatic chasms in the state.”. Here’s a happy group of hikers exploring Columbia River Gorge Gorge around 1910 becoming a part of the Oneonta Gorge History. This slot canyon within the Columbia River Gorge and on the scenic Historic Columbia River Highway has been a popular location to explore for a very long time. Today on a hot Summer day it can be elbow to elbow with.
Welcome to Canyoneering Northwest, the first website devoted to sharing information and ideas for exploring the canyons of the northwest. The purpose of this site is to encourage canyon exploration, share beta, exchange ideas, provide trip reports, help northwest canyoneers connect with one another, and promote safe and responsible canyoneering. This site is guided by the ideals of openness and sharing. It is intended to be noncompetitive and nonjudgmental.
The word canyoneering as used here refers to both technical and nontechnical aspects of the sport. This site includes canyons that are easy, hard, wet or dry. The northwest includes Oregon, Washington, Idaho, and Western Canada.
This sight consists primarily of route descriptions and suggested places for canyon exploration. Canyoneering in the northwest is in its infancy. Only a tiny fraction of the possibilities have any record of descent by canyoneers. If any one reads one of the prospects on this site and goes out and descends it before the rest of us, be assured that no ones feelings will be hurt. Please provide a trip report in order to share your experience with others.
In the brief time that this website has been in existence, it has improved and expanded due to the generous contributions of people who have supplied route descriptions, canyon beta, pictures and suggestions. Credit is always given unless people wish to remain anonymous. Canyoneeringnorthwest is not about the adventures of any one person. The future usefulness of the website will depend on the active participation and openness of northwest canyoneers. There are too few of us to form cliques and keep canyons secret from one another. Please share your canyon explorations with all in a spirit of generosity and goodwill. All trip reports are gratefully accepted and can be e-mailed to canyoneeringnorthwest@yahoo.com

The Fraser Canyon is a major landform of the Fraser River where it descends rapidly through narrow rock gorges in the Coast Mountains en route from the Interior Plateau of British Columbia to the Fraser Valley. Colloquially, the term 'Fraser Canyon' is often used to include the Thompson Canyon from Lytton to Ashcroft, since they form the same highway route which most people are familiar with, although it is actually reckoned to begin above Williams Lake, British Columbia at Soda Creek Canyon near the town of the same name.[citation needed]
Geology[edit]
The canyon was formed during the Miocene period (23.7–5.3 million years ago) by the river cutting into the uplifting Interior Plateau. From the northern Cariboo to Fountain, the river follows the line of the huge Fraser Fault, which runs on a north–south axis and meets the Yalakom Fault a few miles downstream from Lillooet. Exposures of lava flows are present in cliffs along the Fraser Canyon. They represent volcanic activity in the southern Chilcotin Group during the Pliocene period and the volcanic vents of their origins have not been discovered.
Geography[edit]
(the valley coming in at left)
The canyon extends 270 kilometres (170 mi) north of Yale to the confluence of the Chilcotin River. Its southern stretch is a major transportation corridor to the Interior from 'the Coast', with the Canadian National and Canadian Pacific Railways and the Trans-Canada Highway carved out of its rock faces, with many of the canyon's side-crevasses spanned by bridges and trestles. Prior to the double-tracking of those railways and major upgrades to Highway 1 (the Trans Canada Highway), travel through the canyon was even more precarious than it is now. During the frontier era it was a major obstacle between the Lower Mainland and the Interior Plateau, and the slender trails along its rocky walls - many of them little better than notches cut into granite, with a few handholds - were compared to goat-tracks.
North of Lytton, it is followed by BC Highway 12, then from Lillooet to Pavilion by BC Hwy 99 (the farther end of the Sea-to-Sky Highway, though not carrying that name in this area). The British Columbia Railway (the BC Railway is now owned and operated by the CN) line follows the same stretch of canyon from Lillooet to just beyond Pavilion. Between there and the mouth of the Chilcotin River there are only rough ranching roads, and the terrain is a mix of canyon depths flanked by arid benchland and high plateau. Between Pavilion and Lillooet, the river's gorge is at its maximum depth, with the river throttled through a series of narrow gorges flanked by high cliffs, though still flanked above those cliffs by wide benchlands which stand on the foreshoulder of the mountain ranges flanking the gorge.
Hells Gate[edit]
At Hells Gate, near Boston Bar, the canyon walls rise about 1,000 metres (3,300 ft) above the rapids. Fish ladders along the river's side permit migrating salmon to bypass a rockslide that diverted the river during the blasting of the Canadian Northern Railway line in 1913. The area around Hell's Gate carries the name Black Canyon, which may either be a reference to the colour of the rocks when it rains, or the name of a community built on the cliffsides here during the Fraser Canyon Gold Rush. At the site that once housed railway workers, a tourist attraction built in 1971 takes visitors across Hell's Gate via an aerial tramway.
At Siska, a few minutes south of Lytton, there are the Cisco bridges—a pair of railway bridges at the throat of a rocky gorge. From south to north, the Canadian Pacific has been on the west side of the canyon, while the Canadian National has been on the east side. At Siska, the two railways switch sides: the CP—520-foot-long (160 m) truss bridge—crosses to the east, the CN—on an 810-foot (250 m) steel-arched bridge over the CP—is now on the west. The two railways now have an agreement to allow directional running through the canyon as far as Basque. All eastbound trains—CN, CP, and Via Rail's eastbound Canadian—run on the CP line. All westbound trains—CN, CP, Via Rail's westbound Canadian—use the CN tracks.
Upper Fraser Canyon[edit]
Just north of Lillooet, narrow rock ledges choke the river just at the confluence of the lower canyon of the Bridge River, forming an obstacle to migrating fish that has made this spot the busiest aboriginal fishing site on the river, from ancient times to the present. Concentrations of First Nations people here, from all tribes of the Interior, were believed to have been in excess of 10,000.
Sub-canyons[edit]
Many stretches of the Fraser are named in their own right, starting with the Little Canyon between Yale and Spuzzum, which is officially the lowest reach of the Fraser Canyon (although in regional terms Hope, 20 miles (32 km) farther south, is considered a canyon town and to be the southern outlet of the canyon because the highway became more difficult from that point; the river is navigable to Yale). Between the Spuzzum and Boston Bar was known in the gold rush as the Big Canyon or Black Canyon;[1] there are several named subcanyons of the Big Canyon, most famously Hells Gate Canyon (in some descriptions the Black Canyon is below Hell's Gate). Above the Big Canyon there are the Lillooet Canyon, Fountain Canyon, Glen Fraser Canyon, Moran Canyon, High Bar Canyon, French Bar Canyon and more all the way up to Soda Creek Canyon near Quesnel. Upstream from there the river flows in wider country, but in the Robson Valley between Prince George and Tête Jaune Cache, the river enters the Grand Canyon of the Fraser. The Black Canyon was the site of a shantytown of the same name, much of which was on catwalks on the ramparts of its dark-rock cliffs.

Nearly all tributaries of the Fraser have canyons of varying scale; the few exceptions include the Pitt and the Chilliwack in the Lower Fraser Valley. The Thompson Canyon, from Lytton to Ashcroft, is a sequence of large canyons of its own, some of them also named, although most British Columbians and travellers think of it as part of the Fraser Canyon. Other important canyons on tributaries include Coquihalla Canyon, the Bridge River Canyon, Seton Canyon and adjacent Cayoosh Canyon, Pavilion Canyon, Vermilion Canyon (Slok Creek) and Churn Creek Canyon. The Chilcotin River also has several subcanyons, as does the Chilko River, notably Lava Canyon and another Black Canyon.
Upper canyons[edit]
There are other canyons on the Fraser that are not considered part of the canyon, notably at Soda Creek, between Williams Lake and Prince George. The official but comparatively diminutive Grand Canyon of the Fraser is in the river's upper stretch through the Rocky Mountain Trench, about 115 km (71 mi) upstream from Prince George and about 20 km (12 mi) upstream from the Fraser's confluence with the Bowron River. Despite its name, the Grand Canyon of the Fraser is only one treacherous switchback rapid in a shallow rock gorge, and it has neither the roughness of water nor the depth and severity of canyon as is found in the area south from Big Bar to Lillooet or between Boston Bar and Yale.
Almost all of the rivers and creeks feeding the Fraser from Williams Lake south have their own canyons which open onto the Fraser, or are just up side-valleys a few miles. These include Marble Canyon, Churn Creek, the Chilcotin River, the Bridge River, Seton Lake and Cayoosh Creek, the Stein River, the Nahatlatch River, the Coquihalla River and the innumerable smaller creeks flanking the river between Kanaka Bar and Yale.
Tunnels[edit]
The Canadian Pacific Railway has at least 30 tunnels in its Yale to Lytton section with one up to half a mile in length.The Fraser Canyon Highway Tunnels were constructed from the spring of 1957 to 1964 as part of the Trans-Canada Highway project. There are seven tunnels in total, the shortest being about 57 metres (187 ft); the longest, however, is about 610 metres (2,000 ft) and is one of North America's longest. They are situated between Yale and Boston Bar.
In order from south to north, they are: Yale (completed 1963), Saddle Rock (1958), Sailor Bar (1959), Alexandra (1964), Hell's Gate (1960), Ferrabee (1964) and China Bar (1961). The Hell's Gate tunnel is the only tunnel that does not have lights, while the China Bar tunnel is the only tunnel that requires ventilation.
The China Bar and Alexandra tunnels have warning lights that are activated by cyclists before they enter the tunnels. This was required because the tunnels are curved. It is expected that the Ferrabee tunnel will get the same warning lights as it too is curved.
History[edit]
Slot Canyon Columbia River Gorge Rafting
At the mouth of the Canyon, an archeological site documents the presence of the Stó:lō people in the area from the early Holocene period, 8,000 to 10,000 years ago after the retreat of the Fraser Glacier. Research farther upriver at the Keatley Creek Archaeological Site, near Pavilion, is dated to 8000 BP, when a huge lake filled what is now the canyon above Lillooet, created by a slide a few miles south of the present-day town.
During the Fraser Canyon Gold Rush of 1858–1860, 10,500 miners and an untold number of hangers-on populated its banks and towns. The Fraser Canyon War and the series of events known as McGowan's War occurred during the gold rush. Other important histories connected with the Canyon include the building of the Cariboo Wagon Road and the construction of the Canadian Pacific Railway.
The river is navigable between Boston Bar and Lillooet and also between Big Bar Ferry and Prince George and beyond, although rapids at Soda Canyon and elsewhere were still difficult waters for the many steamboats which piloted the river in the 19th and early 20th centuries. The first sternwheeler to pass the rapids was Skuzzy, which was built with a multiple-compartment hull to preserve her from sinking from rock damage. She was used to haul equipment and supplies during the construction of the Canadian Pacific Railway, beginning in the 1880s.
With the construction of the Canadian Pacific Railway in the 1880s came the destruction of key portions of the Cariboo Wagon Road, as there was no room for both railway and road on the narrow, steep mountainsides above the river. As a result, the towns of Lytton and Boston Bar were cut off from road access with the rest of the province, other than by the difficult wagon road to Lillooet via Fountain. During the automotive age and following the construction of the Canadian Northern Railway in 1904–05, a newer version of the road was built through the canyon. The Fraser Canyon Highway was surveyed in 1920 and constructed in 1924–25 with a through-route available after the completion of the (second) Alexandra Suspension Bridge in 1926. This was known as the Cariboo Highway and Highway 1 until the construction and designation of the Trans-Canada Highway (circa-1962).[2][page needed]
