The cut
839 metres, to scale.
A slice through Webb Canyon 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 · Empire State · 443 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. On one side the ground was still rising 12 km out: the true rim is further away and the canyon deeper.

Canyon located in Grand Teton National Park, in the U. S. state of Wyoming
Webb Canyon is a canyon in United States, cut by the Moose Creek. The relief model measures 839 m from the floor to the lower rim, and 1,376 m to the higher one. Rim to rim it is 18 km wide where the cut was taken.

The river
The Moose Creek runs highest from April to May.
The Moose Creek carries about 1.9 m³/s on average here. It runs highest from April to May, fed by melting snow. It is lowest from August to October and from December to February.

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.
