The only “coasts” in Iowa are along the boundaries marked by the Missouri and Mississippi Rivers. So I took some time to go back through vacation photos to meet the photo challenge of coast.
One of our favorite places to vacation is Astoria, Oregon. It always includes time just watching the waves roll in where the Pacific Ocean meets the mouth of the Columbia River.
The first two photos are looking north toward the state of Washington (which can be seen in the top picture) . The next picture is looking south along the Oregon Coast.
This last image shows the observation platform from which the other pictures were taken.
Thank-you, Frank, for the challenge!
