(Newport, Oregon) – There's always more than meets the eye along the Oregon coast. Wherever you look, there's an untold story, often ancient and maybe spooky (imagine 300 miles of lava flows). In the case of Depoe Bay and Newport, they're brother and sister in a funky, geologic way – and they both have their plot twists. That includes answering a big question about all those whales in the area and an older relative of an attraction in Nye Beach that just died. (All photos Oregon Coast Beach Connection)

Yaquina Head and Cape Foulweather NOT Volcanoes

Those were the theories at one point, but were debunked in the '70s. Newport's Yaquina Head and Cape Foulweather are both the product of the Columbia Basalts: a series of lava flows that scorched across proto-Oregon some 14 million years ago, coming from Eastern Oregon.

The shoreline was some 40 miles to the east then, and these areas were all under water. The lava flows came here and filled up gigantic underwater canyons, probably thousands of flows of millions of years. When they fill up spaces like this it's known as lava deltas, and eventually all the softer material around them eroded away, leaving these shapes. Those rocks, in turn, were eroded even more over the eons, turning into what we now see. Seaside's Tillamook Head and Manzanita's Neahkahnie Mountain were the same thing, among many others.

What's All That Smooth, Rounded Rock at Depoe Bay?

Depoe Bay is basically basalt – that same black rock that's part of the Columbia Basalts. But why does it look smoother than other, similar spots?

According to Dr. Scott Burns, professor of geology at Portland State University, the area around Depoe Bay was, for whatever reason, above ground. He was actually one of the few scientists who's carbon-dated Depoe Bay's rocks.

So here, when the lava flows arrived they would hit the sea and cool into those rounder shapes. It's called pillow basalt, and it's the same thing you see footage of in Hawaii when lava plunges into water there.

These bubbly pillow basalts run from Fishing Rock State Recreation Area down to Rocky Creek State Scenic Viewpoint, roughly four miles on either side of Depoe Bay. You'll notice a big difference at the beginning of Otter Loop Road, at Rodea Point.

Ever wondered how deep those rocks go around Depoe Bay? According to Burns these layers can be hundreds of meters thick. Pillow Basalts of Depoe Bay

More Than One Jump-Off Joe in Newport

Most people are familiar with the famed Jump-Off Joe in Newport's Nye Beach, one of the closest things the coast has to a castle ruin-like structure (there's also that old bunker near Coos Bay).

Much of Newport is made of softer stuff than even the bedrock that sometimes shows at Moolack Beach. These soft, sandstone cliffs didn't take well to the change in currents when the jetties were built in the 1890s, and all of a sudden large outcroppings became shorter ones very quickly.

Then, one broke in half, and there was a giant blob at the tideline while the rest of the cliff dissipated. That blob was known as Jump-Off Joe – the original – and it was a hugely popular attraction through about 1916. The dino-looking rock acquired an arch, which tourists loved. In 1916, that arch fell apart, and then the rest was gone by the '30s.

Locals loved Jump-Off Joe so much they named a second headland immediately south of it as Jump-Off Joe. That, too, acquired an arch and became another huge hit through just about two years ago. In the '90s, that arch fell, and the rest of whittled away until it became absolutely unstable in early 2022. See the full story on both Joe's.

Resident Whales of Depoe Bay: Why?

Most people who are big fans or even beginner fans of whale watching on the Oregon coast know that Depoe Bay bills itself as the Whale Watching Capital, and with good reason. But what does that really mean?

There actually are more whales that hang out here than anywhere else. Of the 200,000 gray whales that wander up and down the west coast of both the Americas, some 200 stop and loiter at various spots.

According to Oregon Department of Fish and Wildlife’s Marine Mammal Program Leader Sheanna Steingass, PhD, in Depoe Bay there's approximately 75 gray whales that like to linger in the Depoe area, becoming what local experts call the “resident whales.” Over the last 30 years, she told Oregon Coast Beach Connection, that's about how many have been documented returning again and again. Some wander off and others come and replace them. There are also other random whales that visit along the way. This doesn't mean there's 75 hangin' out here all the time. The actual number can fluctuate wildly.

Many of them have been ID'd and even named catchy names, like the stalwart Scarback, whose old wounds make her stand out.

Why do gray whales linger at Depoe Bay? It's a great food source, Steingass said, with lots of mycid shrimp living in the kelp forests that are abundant here. In fact, there's a cute and endearing surprise here: Steingass said the knowledge of this place is passed on to their young. The babies acquire a “fondness” for this place, instilled by the mother.
