The cut
448 metres, to scale.
A slice through Ysperklamm 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: Big Ben · 96 m · Eiffel Tower · 330 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 21 °C on the rim. The best months to hike are from May to June and from August to September. The rim freezes at night from November to March. The wettest months are from May to August: in a narrow canyon a flash flood arrives without warning, even from rain upstream.

Ravine in Austria
Ysperklamm is a slot canyon in Austria, cut by the Große Ysper river. The relief model measures 448 m from the floor to the lower rim, and 522 m to the higher one. Rim to rim it is 5.7 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.
