📱 1 to 10 phones · 1 team per phone · Independent codes
In 1805, Meriwether Lewis and William Clark led the Corps of Discovery down the Columbia River, racing toward the Pacific
Journey up the Columbia River to The Dalles' forgotten rapids, following in the footsteps of the Lewis & Clark expedition in 1805.
Step into the shoes of William Clark, co-commander of the Corps of Discovery expedition, and relive the exploration of the 'Long Narrows' and 'Short Narrows' that challenged your journey to the Pacific. Your mission: document these dangerous passages and the Native American trade that thrived there for over 10,000 years. At each stop, open your phone: 19th-century topographic maps overlay modern landscapes, coded messages from Nez Perce interpreters appear on the historic walls of The Dalles. A canoe is revealed in augmented reality on the Columbia River, a logbook comes alive on downtown facades, and the spirits of Sahaptian and Chinookan traders whisper their secrets. Over approximately 165 minutes of walking a 1.5 km route, at your own pace, you trace your own Oregon narrative—that of explorers and pioneers, rapids and trading posts. More than an outdoor escape game: an interactive tour immersed in 200 years of history, with anecdotes revealed at each stop and confidential sites that classic guides overlook.
« I walked down and examined the pass found it narrow, and one verry bad place a little in the narrows I pursued this Chanel which is from 50 to 100 yards wide and Swels and boils with a most Tremendeous manner. »— William Clark, Journal of the Lewis & Clark Expedition, October 25, 1805, The Dalles
The story that haunts this land
Votre parcours commence au The Dalles Riverfront Park, situé au 1100 E 1st St, The Dalles, OR 97058. Ce parc riverain, longeant la puissante Columbia River, fut le point de départ de nombreuses explorations. C'est ici que Meriwether Lewis et William Clark ont navigué en octobre 1805, confrontés aux défis des 'rapides confinés par des murs rocheux' qui ont donné son nom à la ville. Cette zone est un carrefour historique, documenté par des sources archéologiques comme un site de trading amérindien depuis au moins 10 000 ans, bien avant l'arrivée des Européens sur le territoire de l'Oregon.
En poursuivant vers le Columbia Gorge Discovery Center & Museum, vous approfondissez votre compréhension de l'expédition de 1805. Le musée expose des collections dédiées aux rapides historiques, les 'Long Narrows' et 'Short Narrows', des passages que l'expédition de Lewis et Clark dut traverser avec une difficulté extrême. Les expositions mettent également en lumière les cultures Sahaptian et Chinookan, qui contrôlaient le commerce vital à The Dalles, soulignant l'importance stratégique de cette région en tant que frontière culturelle et économique avant la colonisation.
Le quartier des The Dalles Murals District, accessible à pied depuis le Riverfront Park, est une étape visuelle de votre exploration. Ces peintures murales historiques retracent l'histoire locale, y compris l'expédition Lewis & Clark et la traversée des rapides dangereux. Ces œuvres d'art public commémorent les événements clés du fleuve Columbia et l'évolution de la ville, offrant une perspective artistique sur les récits que vous découvrez. Elles illustrent la devise officielle de The Dalles, un terme français-canadien qui évoque la géographie unique du site.
Votre itinéraire vous mène ensuite au Fort Dalles Museum and Anderson Homestead, fondé en 1850. Ce fort militaire et commercial est un témoin de l'histoire post-Lewis & Clark, marquant le début de l'ère des 'fur-traders' et des pionniers dans la région de l'Oregon. Le musée préserve des artefacts de cette période, tandis que l'Homestead Anderson documente la vie quotidienne des premiers colons. Plus loin, le Old Wasco County Courthouse, un bâtiment administratif du XIXe siècle, représente l'architecture et l'organisation de la ville après les grandes explorations, consolidant The Dalles comme un centre urbain majeur.
En terminant votre parcours près du The Dalles Clock Tower et du The Dalles Bridge, vous observez la transformation du paysage. La Clock Tower, monument urbain historique, est un repère de l'évolution de The Dalles, tandis que le pont moderne remplace les passages périlleux que Lewis et Clark durent affronter. Vous emportez avec vous l'image d'une région où l'histoire de l'exploration se mêle aux vestiges des cultures anciennes et à la persévérance des pionniers. Cet "Outdoor Heritage Tourism Oregon" vous aura plongé au cœur du "Columbia River Historic Site", un "National Register of Historic Places — The Dalles" où chaque pas révèle un pan du "Lewis & Clark National Historic Trail" et des "Class V Rapids Historic" qui ont façonné l'identité de cette frontière Sahaptian-Chinookan.
Votre périple s'achève avec une compréhension approfondie de The Dalles, de son rôle de "Fur Trading Post Historic" à son statut de carrefour pour les explorateurs et les cultures amérindiennes. Vous avez parcouru le "Oregon Heritage Trail", déchiffrant les indices laissés par le temps et la nature, et observant comment le fleuve Columbia a été à la fois une voie et un obstacle. Des rapides historiques aux infrastructures modernes, chaque site vous a raconté une partie de l'histoire complexe de cette région de l'Oregon. Vous quittez The Dalles avec le sentiment d'avoir marché sur les traces de géants, ayant percé les secrets des "rapides confinés par des murs rocheux" et des cultures qui les ont habités.
