The mountain was named in 1858 by James Hector after the waterfall or cascade on the southern flanks of the peak.

Continuing upwards, the route ascends along the ridge edge until it reaches the crest where it dips before it rises to the false summit.

While the false summit can be descended at its end, it is much easier to follow a trail around the western side along the exposed foot.

Snow typically blocks this route almost until mid July and attempting it while snowy can entail considerable avalanche risk due to the slabby terrain and exposure.

A long window of clear weather - full day - should be anticipated before attempting this climb, as many climbers have gotten into trouble and needed rescue (or died) when a storm suddenly blows in.
