Even the cargo inside the boats is made of shotcrete.

Captain William Clark Park at Cottonwood Beach occupies 80 acres on the Columbia River where the Lewis & Clark Expedition camped 200 years ago on its return trip up the river. The project created concrete replicas of the expeditionís flotilla of canoes: four ponderosa pine dugout canoes and three western red cedar canoes built by the Chinook tribe.

Shotcrete was used to match the color, texture and contours of the original canoes. A high level of artistic detail brought out the seams, cracks, protrusions and depressions of the expeditionís boats.

Adding to the projectís authenticity, cargo in the canoes ó cedar bark baskets, kegs and an 80-pound chinook salmon ó were also simulated with shotcrete.

Integral and surface colors and sealants were applied to the canoes and cargo to achieve a historically accurate appearance and to protect them from stains, discoloration and damage.

Ready-mix concrete was used for structural footings and the cores of the canoes. The footings anchor the boats against river currents and floods.
