Okay, here's one pic from the beach.

South Jetty, Fort Stevens State Park, Oregon:

On the left, the Pacific Ocean. On the right, the mouth of the mighty Columbia River. The jetty extends into the sea quite a ways; from where I stood, it looked like it'd take a couple of hours or more of rock-traversing just to get to the tip.

Here's the satellite view to give you a sense of scale. This photo was from the observation tower. Later, (as will be seen in a couple of pics to be added later) I was standing on the part where the sandy beach to the north touches the jetty.
