Republic of the Congo Gorge

Gorges de Diosso

60 m from rim to floor.

The cut

60 metres, to scale.

A slice through Gorges de Diosso 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: a two-storey house · 9.0 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.

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.
