The cut
123 metres, to scale.
A slice through Yōrō Gorge 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.

Yōrō Gorge is a canyon in Japan, cut by the Yōrō River. The relief model measures 123 m from the floor to the lower rim, and 153 m to the higher one. Rim to rim it is 1.9 km wide where the cut was taken. It lies within Yōrō Keikoku Okukiyosumi Prefectural Natural Park.

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.
