Class III–IV- Rapid · Cataract Canyon
North Sea
Also known as: North Sea, The North Sea, Lower Rapid 7, Toreva Block rapid
North Sea is the lower section of Rapid 7 in Cataract Canyon — the part of the rapid that rolls out through the Toreva Block boulder field below the main drop. Webb/Belnap/Weisheit identify 'North Sea' (singular) as this specific feature, not a composite of the upper rapids as commercial guide usage sometimes suggests. The irregular, choppy waves through the Toreva blocks give the feature its nautical nickname.
