The cut
221 metres, to scale.
A slice through Johannesbachklamm 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. This is a narrow canyon: the published depth, where there is one, is the better figure.

In July the afternoon reaches 27 °C on the floor, against 24 °C on the rim. The best months to hike are in May and in September. The rim freezes at night from December to March. The wettest months are from May to August: in a narrow canyon a flash flood arrives without warning, even from rain upstream.

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.
