Dorris Ranch National Historic District in Dorris Ranch Living History Filbert Farm
features an agricultural landscape grown old with nature. Dorris Ranch spreads
out below the last low foothills above the Willamette River where it gathers together
two of its branches and flows into the broad Willamette Valley. For over a hundred
years now filberts have been harvested from orchards planted amidst tall forests.
At the higher elevations of the park at the base of the foothills there are oak groves and the entrance to the park. The straight trunks of native Oregon White Oak form crooked branches ending in clumps of small leaves. These trees' dark, conservative foliage stand in contrast to what is sometimes an excess of pure green landscape often seen on the west side of the Cascades in the Pacific Northwest. The pure oak grove shading tall or short green grass is a landscape that is characteristic of the Willamette Valley.
