Five South Oregon Coast Landmarks That Make You Think

(Bandon, Oregon) – Scenic splendor is doled out in great abundance on the whole of the Oregon coast, but there is something special and even more curious about the southern half. It's where bizarre landforms reach gigantic proportions, creating new shapes that stretch the imagination, freaky textures that bend the mind and all the while telling tales that are simply astounding.

Behind what you see on this more primitive, untouched half of the state's beaches is really an extraordinary story much of the time.
National Dunes Rec Area, Florence to Coos Bay
It's a hotspot for dune buggying, sandboarding and simply wandering on a near-ocean desert-like stretch, one with remarkable lines and patterns that appear out of nowhere to bring out the best in any would-be photog.
The National Dunes Recreation Area, starting at Florence, is also known for something much stranger and wilder on rare occasion: singing sands. This is when some very exacting conditions have to be met, causing a singing noise or sometimes what can sound like violins. It's rare here, but it's the only known spot on this coastline to actually make this noise.
Yet there's also something sad happening at the National Dunes Recreation Area: it's disappearing. Thousands of feet of dunes have been lost in the last 80 years because of different invasive plants, including Scotch Broom, Gorse and European Beachgrass. They don't allow the dune sands to move freely in the winds, which keeps them from replenishing. So, now you get more watery areas where trees and shrubs grow, nixing sand dunes around them.
There are groups working on this problem, but scientists estimate the dunes could be gone in 50 years. Oregon Coast Dunes National Rec Area in Trouble, Releases Video

This iconic magnet for manic wave action is a wonderland of geologic fun that simply can't be beat. There's so much going on here it's impossible to cover it in one article, and much of it is out in the open.
Why the waves here go so bonkers has much to do with the tilted angle of the rocks and reef below, which you can plainly see from the large structure directly in front of the cliffs. But there's even more going on than that, which you can see at Why Shore Acres Waves Are So Big: Height Measurement.
The strangely-tilted rock formations here are directly related to the continental shelves that are pushing into each other offshore, echoing the crushing action down below.
Then there are all those myriad of pockmarked holes, weird blobs and other surreal shapes, with each having their own geologic explanation.
Shore Acres is a wild ride, not to mention its nearby curious ghost forest action at Sunset Bay.
Battle Rock, Port Orford

A beautiful and engaging landform to go bouncing around on, this south Oregon coast stalwart tells a rather sad tale with its moniker.
A group of nine men arrived here by steamship in 1851, with guns and cannon in tow to force themselves on the tribal village that sat here. This, of course, did not go over well, and the next few days saw the men (minus their Captain William Tichenor, who snaked off to San Francisco) fighting off an angry mob of locals.
Sadly, they wound up doing all the killing, with the Qua-to-mah sustaining the casualties. The eight invaders managed to slip away in the dead of night. Tichenor returned months later with a whole army and slaughtered most of the tribe.
Face Rock
Bandon's most ancient resident is somewhere beyond 50 million years old, but local tribal tales talk of her being a young Indian princess who strayed too far into the waters with her dog and a group of kittens, with a vengeful being turning them all to stone.
In truth, the rock itself is of a very complex origin – a melange of different rock types that were compressed into this object starting 200 million years and going through to about 50 million years ago. It was likely part of a larger chunk of rock that was then whittled away by time and tide over the millennia. Geologists say it's even possible the 1700 tsunami and quake could've had something to do with carving it out into its current shape. How Bandon's Face Rock Was Created A Wild S. Oregon Coast Geologic Tale
Natural Bridges of Boardman Corridor
But what are they? There is some geologic explanation of the Natural Bridges on the south Oregon coast.
According to Ernest Lund, a famed geologist from the ‘60s through the ‘80s, they were part of a sea cave.
“The ‘bowl' behind the natural bridges probably was formed by collapse of roof rock of intersecting sea caves,” Lund wrote in the ‘70s. “The bridges are what is left of the roofs of the caves.”
So how old are they?
It appears as if they are a part of the Otter Point complex, which has been designated as about 145 to 152 years old – basically what is known as the Tithonian age. However, this analysis based on Oregon Coast Beach Connection research has not yet been verified. It's not yet 100% if they're part of that formation, but is quite likely.
