to create many of the mountainous formations. Other sedimentary rock in the area formed more recently, around 20 million years ago. It is hypothesized that portions of the area were islands during parts of the Eocene era. The entire coast range sits on a convergent tectonic margin interacting with the Juan de Fuca Plate that is subducting beneath North America tectonic plate. The range is part of a broad, plunging structural arch of sedimentary and Tertiary volcanic strata that is being uplifted. Other portions of the mountains consist of marine sedimentary rock. The basalt in the area comes from basalt flows that covered much of Oregon that originated from fissures in the central portion of the state. It was during the middle Miocene period that the range was uplifted in the broad, northeast-plunging arch.
