The cut
215 metres, to scale.
A slice through Apertados 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: Great Pyramid · 139 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.

Landform in Brazil's Chapéu mountains
Apertados Canyon is a canyon in Brazil, cut by the Rio Picuí. The relief model measures 215 m from the floor to the lower rim, and 298 m to the higher one. Rim to rim it is 14 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.
