Como sempre é o caminho, eu finalmente perguntei aqui e então a minha próxima pesquisa localizou a resposta para isso. A resposta é Kennedy River Cascade :
It is a popular stopping point about half way between Port Alberni and Ucluelet/Tofino and a place to take a break before Highway 4 begins to wind its way down to Kennedy Lake. On the west side of the Sutton Pass, the Kennedy River falls down through a cascade of boulders that look like they’ve been tossed there by giants. The water here has worn the rock into smooth sculptures and the unique, and accessible, landscape is popular with tourists.
