Quercus garryana...

...Garry Oak or Oregon White Oak: did you know it is a member of the Beech Tree family? Oak, Ponderosa Pine and, to a lesser degree, Douglas Fir trees make up the woods in this area.

Oregon white oak (Quercus garryana), a broadleaved deciduous hardwood common inland along the Pacific Coast, has the longest north-south distribution among western oaks-from Vancouver Island, British Columbia, to southern California. It is the only native oak in British Columbia and Washington and the principal one in Oregon. 

"Though commonly known as Garry oak in British Columbia, elsewhere it is usually called white oak, post oak, Oregon oak, Brewer oak, or shin oak. Its scientific name was chosen by David Douglas to honor Nicholas Garry, secretary and later deputy governor of the Hudson Bay Company." (William I. Stein)
