means of films, models of the "fish-ladders", etc., about the four-yearly migration cycle of the salmon. It is a climb of a few minutes down a reasonable path to the white, foaming river below. The opposite bank can be reached by means of a swaying suspension bridge.

On average, 200 million gallons of water per minute shoot through the canyon which is only 34 m (112 ft) wide at this point. Normally the river here is about 40 m (130 ft) deep, but when the snow thaws it can rise by more than 20 m (65 ft) within a very short time.

When dynamite was used to provide a way through for the railroad in 1914 a massive rock-fall resulted, thus narrowing the river-bed still further. The estimated 5 million salmon swimming upstream were now no longer able to battle against a river flowing at 37 kmph (23 mph) and so found themselves cut off from their spawning grounds. This resulted in a catastrophic reduction in the numbers of salmon caught in the Fraser River. Therefore from 1944 "fish-ladders" were built, long stepped concrete tunnels through which the water flows comparatively slowly, thus enabling the salmon to pass through Hell's Gate once again. Today more than two million salmon a year successfully negotiate the canyon.

The Hell's Gate Airtram is the best way to view this part of Fraser Canyon.
