The Pacific Ocean occupies the southeastern corner of this maritime chart, representing the vast coastal waters off the Oregon shoreline. This 2011 survey illustrates the precise coordinates and universal transverse mercator grid used for modern marine and land navigation along the coast of Douglas County. While the majority of the quadrangle covers open water, it serves as a critical reference for the boundary where the sea meets the coastal terrain near Pacific Ocean waters. The lack of land-based infrastructure highlights the maritime nature of this specific quadrant, prioritizing hydrographic data and coordinate systems for use by the U.S. Forest Service and other federal agencies managing the Pacific Northwest shoreline.
