The Fraser Canyon is colloquially understood to extend from Lytton to Ashcroft, encompassing the Thompson Canyon, though its technical definition begins higher up the river.

The Fraser Canyon was primarily formed by the Fraser River cutting into the uplifting Interior Plateau during the Miocene epoch.

The Fraser Fault, which the Fraser Canyon follows, runs on a north-south axis and intersects the Yalakom Fault near Lillooet.

The Canadian National Railway and the Trans-Canada Highway are carved into the rock faces of the southern Fraser Canyon.

BC Highway 12 follows the Fraser Canyon north of Lytton, while BC Highway 99 runs alongside it from Lillooet to Pavilion.

The Cisco bridges near Siska are notable because they mark the point where the Canadian Pacific and Canadian National railways switch sides of the Fraser River.

The Canadian Pacific Railway has at least 30 tunnels along its section between Yale and Lytton, with one extending for up to half a mile.

The Fraser Canyon Highway Tunnels were constructed as part of the Trans-Canada Highway project between 1957 and 1964.

The longest of the Fraser Canyon Highway Tunnels is approximately 610 meters (2,000 feet) long, while the shortest measures about 57 meters (187 feet).

The Hell's Gate tunnel is unique for not having lights, while the China Bar tunnel requires a ventilation system.

The warning lights in the China Bar and Alexandra tunnels are designed to alert cyclists before they enter due to the tunnels' curvature.

The Fraser Canyon Highway was surveyed in 1920 and constructed between 1924-1925, eventually being incorporated into the Trans-Canada Highway around 1962.

Warning lights in the China Bar and Alexandra tunnels are activated by cyclists to alert them to the tunnels' curvature.

During the frontier era, trails in the Fraser Canyon were described as precarious, resembling goat-tracks cut into granite, rather than wide and easily navigable paths.

During the Fraser Canyon Gold Rush of 1858-1860, significant historical events included the Fraser Canyon War and McGowan's War.

The sternwheeler "Skuzzy" navigated Fraser River rapids due to its multiple-compartment hull, designed for resilience against rock damage.

The construction of the Canadian Pacific Railway in the 1880s, due to limited space on the narrow mountainsides, led to the destruction of key portions of the Cariboo Wagon Road, cutting off direct road access to towns like Lytton and Boston Bar.

The Dewdney Trail and the Hudson's Bay Brigade Trail are significant historical trails associated with the Fraser Canyon.

The "McGowan's War" was a significant event during the Fraser Canyon Gold Rush, involving disputes over mining claims.

The sternwheeler "Skuzzy" featured a multiple-compartment hull, making it robust against damage from rocks in the Fraser River rapids.

How was travel through the Fraser Canyon characterized during the frontier era?

During which historical period did thousands of miners populate the Fraser Canyon and experience events such as the Fraser Canyon War?

What unique design feature of the sternwheeler "Skuzzy" aided its navigation of the Fraser River rapids?

Hells Gate is located near Boston Bar, where the canyon walls rise approximately 3,300 feet (1,000 meters) above the river.
