There’s something about treasure hunting that’s irresistible and compelling; especially when it touches Oregon history and offers unique outdoor adventures too.
Rich Mulcahy likes to say, “When the tide goes out, the treasure table is set.”
“I think it’s that I am going after something that’s been lost, and I am digging in the sand to find it. I love to dig stuff.”
Rich walks long lonely stretches of the Oregon coast each day accompanied only by the excited sounds of his hand-held detector; the device is his constant companion.
He sweeps the sand with the detector and marks each spot where something’s hidden just below the surface.
He stopped suddenly and took a quick scoop with his shovel and revealed an old car key – most likely an ignition key. Mulcahy quickly smiled and chuckled, “Probably turned into a long day at the beach for someone.”
Most days, Rich said he discovers everyday objects, but he is intrigued by rediscovering history in the beach’s sandy layers too.
His detector can find items in the top three or four inches that date back thirty to fifty years – but it goes back even further - a century or more - when he digs down a foot.
Many of his so called ‘targets’ are easy to recognize items ranging from silver coins to gold wedding rings and other metallic jewelry.
But every now and then he finds real “head scratchers;” like exotic Chinese copper coins that date to the 1700's and even a Roman coin that dates back nearly two thousand years.
“Well, I shouldn’t be surprised given the number of shipwrecks that we’ve had off the Oregon coast,” said Mulcahy. ”I’m sure that there’s material from those old wrecks that have come in with the tide.”
Parts of the Oregon coast are called the “Graveyard of the Pacific” for good reason, according to Dave Pearson with the Columbia River Maritime Museum in Astoria.
As long as mariners have traveled the ocean, ships have wandered too close to shore and been caught by powerful storms. They’ve also been guided by a captain’s poor judgment so the ship and crew often ended in disaster on the beach.
“It’s a dangerous environment,” said Pearson. “Oregon has what mariners call a ‘lee shore’ with all the forces of nature – wind and waves - working against the ship, forcing it to land on shore. Plus, it’s a remote region and there are few places to find refuge.”
Pearson said that some shipwrecks, like the always-visible “Peter Iredale”(Ft Steven's State Park) that wrecked in 1906, symbolize the worst that Mother Nature will do when things don’t go as planned.
The “New Carissa” may be Oregon’s most infamous modern-era shipwreck! It was more than two football fields long, filled with high technology and yet it wrecked off the mouth of Coos Bay, Oregon in 1999.
It has often been called “the ship that would never leave Oregon” because it remained a fixture stuck in the south coast sand for several years before it was finally dismantled.
Pearson said that bad weather and a poor knowledge of Oregon’s coastal dangers were big reasons for the wreck: “Not understanding what the weather can be like on the Oregon coast is a huge mistake. The New Carissa got into trouble and couldn’t turn fast enough to correct her problem.”
Jeff Smith is the Maritime Museum’s Curator and said that there have been over 2,000 shipwrecks at the mouth of the Columbia River alone and 200 of those have been major ships.
The museum is a fine place to see varied wreck relics like a life ring from the 1800’s or blocks of bees wax from the 1700’s.
Still – for all we know about Oregon shipwrecks – Pearson said that there is even more we don’t know: “We haven’t discovered all of the shipwrecks yet – they’re out there, just waiting to be revealed.”
Back on the beach, Rich Mulcahy said that singular thought keeps him warm on cold, rainy days while he hunts for secrets from the tides.
He said that it’s not what he finds but what he might find that keeps him coming back:
“It’s the anticipation. If that thing I find could only talk what would it tell me? What are the circumstances that placed it there? For me, that is something to ponder.”
Rich points out several things you should keep in mind if you decide to head for the coast and try your hand at detecting – first, never turn your back to the ocean because it’s simply not safe. Be sure to check the weather forecast because the weather can change in a heartbeat this time of year.
Finally and critically, the Oregon Parks and Recreation Department manages the public beaches of the state and there are some beaches where detecting isn’t allowed. In fact, you’re not to do any searching around or digging at historic shipwreck or artifact areas or within designated state park properties. Still, most Oregon beaches are open to detecting and for a complete list be sure to check the OPRD Metal Detecting website.
