Pacific Ocean waters dominate this maritime survey off the coast of Southern California. Located within Ventura Co, the map focuses on the open sea north of San Nicolas Island. The only terrestrial detail is found in the extreme southwest corner, where the rising topographic contours indicate the steep northern slopes and cliffs of the island's coastal edge. This specific perspective highlights the geographic isolation of this offshore territory within California state waters, illustrating the stark transition from the deep ocean floor to the sudden verticality of the Channel Islands landmass.
