Capsize Rapid in Cataract Canyon reduced to a boulder field at record-low water, thin channels of the Colorado River threading between exposed rounded rocks below a red talus bank.

Class III–III+ Rapid · Cataract Canyon

Capsize

Mile Long's technical crux. Scouted by most groups.

Also known as: Rapid 15, Hell to Pay, Best

Capsize Rapid (Rapid 15) is one of the signature rapids within the Mile Long Rapid sequence (Rapids 13–19). It is the most technical of the Mile Long rapids and typically requires scouting. A common scouting eddy exists between Rapid 14 and Capsize — though at high water that eddy is not accessible, forcing the group to commit to running the full sequence.
