Sometimes when they do not "show" what works is to pound them up. Besides my clam gun I also carry a stick about the size of a broom handle. I thump the wet sand with one end of the stick as I walk. Every now and then a clam hole will open up or one will shoot water. If I don't thump the sand, then it just looks like flat wet sand. I don't know much about the razor clam situation at Yachats, but if you ever get up to the north end of the state Clatsop County beaches are the place to head. A lot of folks come down to Gearhart beach, park and walk toward the Necanicom River to clam. Others hit Del Ray beach or Sunset Beach. The next best access is at Fort Stevens State Park. If I were prospecting for razors down there I would look for long stretches of sandy beach and go out a couple of hours before a minus tide. Look right were the water is meeting the sand, then look just past that and see if you can locate a sand bar just in from the surf. Be safe, g with a buddy and don't turn your back on the ocean.
