A mosaic of criss-crossing faults extends east of
Corvallis and Albany through the Willamette Valley
and into the Western Cascades (after Yeats, et al.,
1991; Graven, 1990).
Gently folded Tertiary marine sediments in the
southern Willamette Valley are cut by the Pierce
Creek fault north of Eugene (after Yeats, et al.,
1991; Graven, 1990).
