Structurally the strata just described are involved in the 

 badly wrinkled southwestern limb of a syncline whose axis 

 trends from Port Crescent northwesterly diagonally across the 

 Strait of Juan de Fuca. The strata forming the northeasterly 

 limb occur fringing the south coast of Vancouver Island. 



Deposits of Oligocene age are well developed in the low 

 clififs along the entrance to the Bremerton Navy Yard. These 

 beds are a continuation of those occurring to the east at Alki 

 Point and South Seattle, as well as along the north flanks of 

 the Newcastle Hills. They have been sharply folded and 

 deeply dissected by erosion, and later covered with deposits 

 of glacial drift. The following generalized stratigraphic sec- 

 tion has been constructed. The lowest beds exposed in the 

 section outcrop at Orchard Point on the south side of Brem-
