The cut
1,947 metres, to scale.
A slice through Goye di Hône where it is deepest and narrowest, measured on the Copernicus relief model every 30 m. Same scale as the landmark standing on the floor.

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.

Goye di Hône is a canyon in Italy, cut by the Dora Baltea river. The relief model measures 1,947 m from the floor to the lower rim. Rim to rim it is 11 km wide where the cut was taken.

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.
