Class IV Rapid · Cataract Canyon

Big Drop 2

Features: Marker Rock, Little Niagara, Fang Rocks, Ledge Wave, Red Wall, Window.

Also known as: Rapid 22, Little Niagara zone

Big Drop 2 is one of Cataract Canyon’s most consequential rapids and is frequently the crux for raft crews. It is known for large breaking features, fast recovery demands, and the potential to flush mistakes into Big Drop 3.

Difficulty

Class IV through most of the runnable range. Above 50,000 cfs (rare big-snow runoff), Webb, Belnap and Weisheit warn, the canyon can be very dangerous and boats frequently flip. Treat Big Drop 2 as a flow-dependent expert rapid with whole-sequence consequence rather than a stand-alone move.

The water

Character: big water.

Features: ledge-like entrance behavior at some flows; large breaking waves; fast-moving center tongue; explosive tailwater.

Hazards: Little Niagara feature at some flows; boat flips or ejections with limited recovery time; immediate carry-over toward Big Drop 3.

How it changes with flow

Low water: Can be more technical and structure-defined, with less forgiveness for poor angle and slower boats.

Medium: Often the classic Cataract crux: large waves, fast reaction time, and heavy consequence for swimmers.

High water: Behaves as big water, with very large hydraulics and a strong chance of downstream compounding into Big Drop 3. Above 50,000 cfs, Webb, Belnap and Weisheit warn, the canyon can be very dangerous and boats frequently flip.

Scouting

Usually scouted as part of the Big Drops sequence. Precise line language should be tied to your future flow-calibrated rapid notes rather than this base entity.

Swim consequences

Very high. Historic incident reports describe swimmers and overturned rafts continuing into Big Drop 3 and beyond.

Commonly run in: oar raft, paddle raft, cataraft, hard shell kayak.
