Historically, the bluff was within the home range of the Chinook tribe, whose territory was the banks of the Columbia River from the mouth, Northward up the coast of present-day Washington state and up-river to the historic site of Fort Vancouver. Pre-contact, the rich lands of the Chinook provided an abundance of food - salmon, elk and deer, wapato, camas and acorns to name a few. Through this wealth of natural resources, they were able to live a seasonally nomadic lifestyle, living in permanent cedar plank houses along the banks of the Columbia and its tributaries in the Winter and in temporary shelters in the Summer months while foraging, hunting and fishing.
Though the Chinook didn't practice agriculture like many other North American tribes, they were very instrumental in the formation of the many Oregon Oak and camas plant communities that once dotted the Willamette Valley and Columbia River basin. Through low-intensity burns, usually carried out in the late Summer or Fall, the Chinook and other tribes throughout the Pacific Northwest would "burn out" the Douglas Firs, brush and weeds, which in turn would encourage the camas and oak to thrive and attract game to open prairies. Arrowheads found on the site in the past indicate that the bluff was once a hunting ground. The presence of the oak, camas, yampah, tarweed and medicinal plants is an indicator that the site was also at one time, frequented for harvest of these traditional food staples .
Today the bluff is a fragment of this vanishing oak and camas landscape and a living legacy to a people whose culture and ways were severely impacted by disease and displacement in the early 19th century.
