The prevailing Pacific currents along the shores of the west coast of North America is to the north so any silt brought down by the rivers draining into the ocean tends to settle to the north of the river. This is most obvious at the mouth of the Columbia. After picking up silt along its thousands of miles course, the Columbia finally releases it into the sea at Cape Disappointment. Those ocean currents push it all to the north where Washington’s Long Beach Peninsula has been created. The Peninsula in turn, protects Willapa Bay.
About the map.
We photographers have a tendency to trample and ruin a good spot because so many people visit. For this reason, I don\’t always provide a precise geo-tag on these maps. They are intended to give you a general idea of the location, not the tripod marks.
