When Champlain travelled up the Ottawa River in 1613, he used two Aboriginal portages to bypass the falls known to the Algonquins as Asticou, meaning "cauldron" or "chaudière". Until the mid-19th century, these portages enabled explorers, missionaries, fur traders, and voyageurs to continue their journey westward. Industrial development has erased the downstream trail, but the second trail remains near present day Brébeuf Park, recalling the importance of the Ottawa River as a key passageway to the interior of the continent. *Note: This designation has been identified for review.
