The cut
145 metres, to scale.
A slice through Lava Canyon where it is deepest and narrowest, measured on the Copernicus relief model every 30 m. Same scale as the landmark standing on the floor.
Standing on the floor, to scale: Big Ben · 96 m
Depth is measured to the lower rim; the width is from rim to rim. A 30 m relief model smooths the narrowest walls, so a slot canyon reads shallower than it is.

The river
The Chilko River runs highest from January to June.
The Chilko River carries about 18 m³/s on average here. It runs highest from January to June, fed by melting snow.

Recent years
Wet years, dry years.
Rain of each month as a share of the 1991–2020 average. A dry year means a lower river and hotter rock; a wet one, more water in the gorge.
