The cut
1,534 metres, to scale.
A slice through Renjhihguan 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: Eiffel Tower · 330 m · Burj Khalifa · 828 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. On one side the ground was still rising 12 km out: the true rim is further away and the canyon deeper.

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.
