The cut
1,116 metres, to scale.
A slice through Garnitzenklamm where it is deepest and narrowest, measured on the Copernicus relief model every 30 m. Same scale as the landmark standing on the floor.

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 26 °C on the floor, against 18 °C on the rim. The best months to hike are in September. The rim freezes at night from November to April. The wettest months are in August: in a narrow canyon a flash flood arrives without warning, even from rain upstream.

Garnitzenklamm is a slot canyon in Austria, cut by the Kreuzgraben river. The relief model measures 1,116 m from the floor to the lower rim. Rim to rim it is 9.0 km wide where the cut was taken.

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.
