The cut
171 metres, to scale.
A slice through Twannbachschlucht 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.

The river
The Twannbach runs highest from March to August, in October and from December to January.
The Twannbach carries about 61 m³/s on average here.

- 46 m³/sDec
From about 31 m³/s in the lowest month to 91 m³/s in the highest. Its basin above this point covers 2,622 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.
