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 just a few. Through this wealth of natural abundance, 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, unlike many other North American tribes,  the Chinook were not known to practice agriculture, they were very instrumental in the shaping and maintainance of the many Oregon Oak and camas meadows 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.  To this day, the presence of the oak, camas, yampah, tarweed and other food and medicinal plants found on Liberty Hill is an indicator that the site was frequented for harvest of these traditional staples .

​

Today the bluff is a fragment of this vanishing oak and camas landscape and a living legacy of a people whose culture and ways were severely impacted by disease and displacement in the early 19th century.
