The cut
1,719 metres, to scale.
A slice through Vorderkaserklamm 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. This is a narrow canyon: the published depth, where there is one, is the better figure.

In July the afternoon reaches 24 °C on the floor, against 12 °C on the rim. The best months to hike are from June to August. The rim freezes at night from September to May. The wettest months are from June to August: in a narrow canyon a flash flood arrives without warning, even from rain upstream.

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.
