The cut
918 metres, to scale.
A slice through Tolmin Gorges 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 29 °C on the floor, against 22 °C on the rim. The best months to hike are in May and from September to October. The rim freezes at night from December to March. The wettest months are in November: in a narrow canyon a flash flood arrives without warning, even from rain upstream.

Tolmin Gorges is a slot canyon in Slovenia, cut by the Soča river. The relief model measures 918 m from the floor to the lower rim, and 1,062 m to the higher one. Rim to rim it is 15 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.
