The cut
325 metres, to scale.
A slice through Geibikei 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.

Geibikei is a canyon in Japan, cut by the Satetsu River. The relief model measures 325 m from the floor to the lower rim, and 387 m to the higher one. Rim to rim it is 6.0 km wide where the cut was taken.

From about 3.4 m³/s in the lowest month to 15 m³/s in the highest. Its basin above this point covers 302 km².
Estimate: long-term flow from the HydroATLAS model (WaterGAP, 1971–2000) shaped by the monthly rain, snow and temperature of the area (NASA POWER). Dams change it. Not a forecast.

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.
